This may not be the "perfect and complete" answer, but what I do to run a program
on different platforms is to use a batch file which defines the common blocks
(oh, yes I use common blocks!) and defines the platform specific path names,
directory separators etc.
Here is the main part of the batch file as an example:

========== snipped some code here ==========
; on which computer is it running
; this list can be extended in future if neccessary

; you have to edit this datapath and the filepath for the programs
case !version.arch of $
"sparc": begin $
data_path='/disks/sprite/disk2/hfrey/ago/' &$
file_path='/disks/sprite/disk1/hfrey/idl/ago/' &$
dir_sep='/' &$
dev_name='X' &$
end &$
"PowerMac": begin $
data_path='+Hard Disk:applications:IDL:IDL 4.0:ago' &$
file_path='+Hard Disk:applications:IDL:IDL 4.0:ago' &$
dir_sep=':' &$
dev_name='MAC' &$
end &$
"alpha": begin $
data_path='[hfr.idl.ago.data' &$
file_path='[hfr.idl.ago ' &$
dir_sep='.' &$
dev_name='X' &$
end &$
else: begin $
print,'You have to edit the case statement in ago_config.cmn' &$
stop &$
end &$
endcase
================ end of batch ==============================

All my procedures call this batch at the beginning with

@ago_config.cmn

and you might include the platform specific differences in the directory creation
here as well.
