Hi,
I usually run IDL from the command line and it inherits all the
environment variables I have in my .profile. This allows me to, for
example, "spawn, 'foo'" where foo is in my unix PATH, and foo is
found. When I run the IDLDE by double-clicking on the icon, this does
not work.
I've found the suggestion to create a ~/.MacOSX/environment.plist file
and put my path there. This has caused all sorts of other problems.
Is there a way in the IDLDE, or via IDL commands (I can put them in my
startup.pro file), for me to generally get my environment into the
IDLDE or specifically append my PATH statement so that some unix tools
can be found by SPAWN?
Thanks,
-k.

I know this is a really old thread, but since this is where I landed in my great search on this issue.. in 2017.. I figured I'd post my solution since I cannot seem to make anything else work. This is code you can put in your startup.pro file, and it assumes you declare your environmental vars with the export command in your .bash_profile. Change the relevant lines as needed. Works like a charm for me.. after all these years of declaring pathnames explicitly for all my scripts run in my IDLDE environment.
;Set user environmental variables
file = getenv('HOME')+path_sep()+'.bash_profile'
line = ''
openr, lun, file, /get_lun
while not eof(lun) do begin & $
readf, lun, line & $
if strcmp(line, 'export ', 7, /fold_case) then begin & $
temp = strsplit(strmid(line, 7), '=', /extract) & $
env = strsplit(temp[1], path_sep(), /extract, count=n) & $
for ienv=0, n-1 do $
if strcmp(env[ienv], '$', 1) then $
env[ienv] = getenv(strmid(env[ienv],1)) & $
if product(strlen(env) gt 0) then $
setenv, temp[0]+'='+strjoin(env, path_sep()) & $
endif & $
endwhile
free_lun, lun
