[GUSDEV] gusEnv.bash does not set PERL5LIB. Bug?

[John I. <io...@gm...>]

gusEnv.bash sets some environment variables, including PATH, but it doesn't
set PERL5LIB. Isn't that a bug?

I call gusEnv.bash in my .bash_profile, then do this:
PERL5LIB=${GUS_HOME}/lib/perl:${PERL5LIB}

But if I use gusEnv.bash later in the session, to point at a different GUS
install, PERL5LIB continues to point wherever it started.

This is a bug, right? I'm running executables from the new gus_home, but
they're finding their Perl modules in the old gus_home/lib/perl. I think
that line above should be in gusEnv.bash, so it happens whenever we switch
environments. What do you think?
