source bash config from perl code

[Oleg Goldshmidt]

This has gotten out of hand, I think. The OP wanted to run a perl
script in a custom environment set in a bash script, and we went off
on a tangent in the direction of something quite general.

This is a very good example of how an attempt to create a general,
portable, robust solution for something that looks quite simple can
lead to (likely unwarranted) complications. In some cases the
complications may be unavoidable, but then this becomes way out of
scope for a mailing list. It becomes a non-trivial project that must
be specified, scheduled, budgeted, QA'ed, etc.

Alex, sorry, this is probably not what you needed. Mea culpa, I only
wanted to point out that you shouldn't execute your perl script
without being sure that the environment is set correctly. I am sure
you didn't need me for that, either. ;-)
