See FAQ #2:

IDLWAVE essentially just does the equivalent of "type 'idl' at the
shell prompt" to load the program, so this has to "do the right thing"
in order for it to work. I don't know how your IDLWAVE could be
launching an XTerm, but I'd guess that you might have a shell script
called "idl" which launches an XTerm and runs IDL inside of it, or
something similar. This would of course confuses IDLWAVE, and cause it
to shut down the process (which is why it later claims you need to run
it). If that's the case, I'd add this to your ~/.emacs file:
(setq idlwave-shell-explicit-file-name "/usr/local/rsi/idl/bin/idl")
or wherever you put your IDL install.
By the way, if you find you'd like a command to "pull up a quick IDL
session", and that's what motivated your xterm popup, you might like
to read the hint in this old IDLWAVE announcment:
http://idlwave.org/announce/announce_4.16.txt
which describes a way to quickly launch the IDLWAVE shell in a window by
itself. It still works great with v6.0.
Another morsel of IDLWAVE news... those of you following Emacs 22 and
the gradual build-up to release will be pleased to know that IDLWAVE
v6.0 is now integrated into the Emacs CVS and will be included in the
new release. A variety of niggling little problems that used to
plague IDLWAVE under v21.X are now fully resolved in 22.X, and for me
it's by far the best and most stable IDLWAVE environment.
