[Bioperl-l] darwin PERL5LIB ignored

[Allen Day]

This is an off-topic question for the list, but I know there are lot of 
mac users here, and I'm hoping for a quick fix.

I'm having problems getting my bash environment to recognize my $PERL5LIB 
variable.  Even if I declare the variable in my .bashrc file and source 
it, the variable is ignored until I explicitly export it from my session 
prompt.  Below is a dialog illustrating the problem.

Anyone know of a workaround to get perl to use $PERL5LIB as declared in
the .bashrc file, as opposed to requiring an explicit export of the
variable?

Thanks.
