Hi David,

As far as I can tell Perl on a Mac pays absolutely no attention the  
environmental variable PERL5LIB. I have eliminated all PERL5LIB  
specifications on my machine.

Here are a couple of test scripts that illustrate my point.

Script 1
    [put either shebang line here]

    #!/usr/bin/perl -w
    #!/opt/local/bin/perl -w

    # test1.pl  - Test Perl constructs

    use strict;
    use Date::Format;

Script 2
    [put either shebang line here]

    #!/usr/bin/perl -w
    #!/opt/local/bin/perl -w

    # test2.pl  - Test Perl constructs

    use strict;
    use Crypt::SSLeay;

When I run Script 1, either from Terminal or from BBEdit, nothing  
happens with the top shebang line (Date::Format is in my /usr/bin/ 
perl [5.8.6] tree), but I get an error message listing @INC with the  
bottom shebang line (Date::Format is not in my /opt/local/bin/perl  
[5.8.8] tree).

Just the opposite situation occurs when I run Script 2, either from  
Terminal or from BBEdit. I get an error message listing @INC with top  
bottom shebang line (Crypt::SSLeay is not in my /usr/bin/perl [5.8.6]  
tree), but nothing happens with the bottom shebang line  
(Crypt::SSLeay is in my /opt/local/bin/perl [5.8.8] tree).

I have found no way of running a module in one Perl tree with the  
other version of Perl.

Regards,

Vic
