Perl DBI problem.

When I try to install the CPAN module DBI on Mac Tiger, it fails even
with force. When I scroll back through the output I find the
following error message:


"Can't locate Data/Dumper.pm in @INC" (followed by a long list of
directories.)


But I installed Data::Dumper with no problems.

I know what you're going to say: "It's not installed in one of the
directories listed." Point well taken, but WHERE is it being
installed, and where does this mysterious and bizarre @INC array get
its paths in the first place, and how do I modify it? Please don't
say "push, pop, shift, and,or unshift", because I've used those, but
the @INC array has a non-persistence property when it comes to my
directories, but is very stubbornly persistent about its own
directories. Where does this array hide when I'm not using Perl?

When I try to install the CPAN module DBI on Mac Tiger, it fails even =20
with force. When I scroll back through the output I find the =20
following error message:

But I installed Data::Dumper with no problems.

[rr] Where is it? What is the output of 'perl -V'?

[rr] @INC is defined when you build Perl. When you build and install
modules, they are written to a directory under @INC. See
http://search.cpan.org/dist/perl/pod/perlvar.pod for information about
@INC.

If you installed Data::Dumper in a non standard directory, you will need
to use the 'lib' pragma to define where this is located. See
http://search.cpan.org/dist/perl/pod/perlmodlib.pod#Pragmati c_Modules
for information about this.

The 'push' etc. built-in subroutines are not designed to be persistent,
so you are correct in your observation.
