Well, I don't think compilation is a problem, e.g. the program

pro test,dum
if keyword_set(dum) then a = some_program(3) else print,'AOK'
return
end

will run fine so long as one doesn't try to access Some_program().

IDL> test
% Compiled module: TEST.
AOK
IDL> test,1
% Variable is undefined: SOME_PROGRAM.
% Execution halted at: TEST 2 /Volumes/Apps_and_Docs/
landsman/codev/test.pro

(If I had added a compile_opt idl2 at the beginning, it would also
know that SOME_PROGRAM is an underined function/procedure rather than
a variable.)
Similarly, legend.pro should now run fine without symcat.pro in one's !
path, so long as one doesn't try to use a value of PSYM>=11.

But I agree the more general question is difficult. Currently, I
keep JHUAPL routines I need in a separate directory, and tell users to
delete the directory if they have the entire JHUAPL library
installed.
