I'm in the middle of our (RPI) end-of-semester crunch, so I haven't had
the time to review all of this and make sure I understand what the
issues are.

However, I will note that FreeBSD's 'env' command includes an option
for setting the path's to search.  It also includes the '-S' option,
which is important for getting the '-P' option to work correctly
when used on a shebang line.

These are FreeBSD-specific extensions, so they wouldn't help if you
want to write portable code.  But I think they should help for some
of the issues which people have described in this thread.
