Sorry, Damiano, I didn't read your question properly. I just went
and assumed that you intended *other* people to run your programs.
(This is what we'd call an extreme case of "Send button syndrome", I guess.)
Anyway, I see that someone else has posted a sensible answer.

If I understand you correctly, you can achieve what you want by
adding your local directory to the environment variable IDL_PATH.
Include the following command in your startup file:
C shell:
setenv IDL_PATH \+/your_local_dir:\+$IDL_DIR/lib:\+$IDL_DIR/examples
Korn shell:
IDL_PATH=\+/your_local_dir:\+$IDL_DIR/lib:\+$IDL_DIR/example s
export IDL_PATH
Any directories beneath /your_local_dir will be included in IDL's
system variable !PATH that it uses to find routines. (The "+" means
that subdirectories are included.)

I think you may have overcomplicated things a bit. What you say is true if
Damiano wanted to install routines such that they were picked up by everybody
logging into that computer, but that possibility wasn't discussed in the
original post.
As has already been pointed out, the simplest way to do what Damiano asked was
to define IDL_PATH to point to his directory. He doesn't need superuser
permission for that, so long as he's only doing it for himself.

There are a couple of solutions that come to mind, but I think that you'll
need superuser permission to implement any of them. So since you're probably
going to have to involve your systems manager regardless, why not just get him/
her to create a directory for you under $IDL_DIR/lib? If this is going to
be a problem, here are some other things you could try...
First of all, put your programs in some directory of your own, make this
directry world -readable and -executable, and make all the programs
world-readable. (If the people who are going to run your programs are
in the same group as you then you can use group instead of world access,
which is preferrable.)
(If there's much IDL development going on at your site then you should consider
persuading your systems manager to create a group-accessible directory
structure for the progs, rather than having you set up a directory in your
private user area.)
Then implement one of the following:
1 Add your directory to the IDL_PATH for all your programs' users.
e.g., If your programs are in /users/damiano/idlstuff and IDL_PATH is
'.:+$IDL_DIR/lib' then you must change it to look like:
'.:+$IDL_DIR/lib:/users/damiano/idlstuff', or
'.:+$IDL_DIR/lib:+/users/damiano/idlstuff' (note the "+") if there are
subdirectories under idlstuff.
Where do you do this?
Some people define IDL_PATH privately, in one of their startup files
(typically in .login). In such cases you will need to edit the .login
files (for each user), and you'll need SU privs for this. (Well, you
could ask all the users to do the change themselves.)
Some people use a "global" setup file called idl_setup, which lives in
$IDL_DIR/lib. e.g., They "source" this file from their .login. In this
case you'll just need to modify $IDL_DIR/bin/idl_setup, but again you'll
need SU privs for this. (Also, you might need to redo this whenever you
upgrade IDL.)
2 Set up (or get the systems manager to set up) a symbolic link in $IDL_DIR/lib
which points to your directory. e.g.,
%>cd $IDL_DIR/lib
%>ln -s /users/damiano/idlstuff damiano
(Actually, I'm not sure of the syntax on AIX - this e.g. is for OSF.)
This option has some problems.
The first problem - and this is quite a noticeable one - is that:
*** it doesn't actually work with IDL4.0.1 ***
IDL4.0.1 doesn't appear to follow symbolic links when it builds its !path
variable. You'll have to wait for IDL5. (Hopefully not that long, which
is why I mentioned this option at all.)
Secondly, you might have to redo the link whenever you upgrade IDL.
Thirdly, the $IDL_DIR/lib entry in IDL_PATH must be a "recursive" entry,
i.e., it must be preceded by a "+".
And, of course, you'll need SU privs to create the link.

You need to update your IDL_PATH system variable so that
it can locate the directory where you store your own library
files. There's some more info about this in the section under
Environment Variables in the user manual. You can either do
it external to IDL by updating IDL_PATH, or internally by
updating the !path system variable.
