[PLUG] Fix Perl Location for CPAN

[Rich Shepard]

   If I correctly read /var/log/httpd/error_log, I _think_ I need to upgrade
DBD::Pg. I tried to do so but ran into an error I've not before seen:

   CPAN.pm: Going to build T/TU/TURNSTEP/DBD-Pg-2.17.2.tar.gz

Configuring DBD::Pg 2.17.2
PostgreSQL version: 90001 (default port: 5432)
POSTGRES_HOME: (not set)
POSTGRES_INCLUDE: /include
POSTGRES_LIB: /lib
OS: linux
The value of POSTGRES_INCLUDE points to a non-existent directory: /include
Cannot build unless the directories exist, exiting.
No 'Makefile' created  TURNSTEP/DBD-Pg-2.17.2.tar.gz
   /usr/bin/perl5.10.1 Makefile.PL -- NOT OK
Running make test
   Make had some problems, won't test
Running make install
   Make had some problems, won't install
Failed during this command:
  TURNSTEP/DBD-Pg-2.17.2.tar.gz                : writemakefile NO -- No

   Please tell me how to fix to the problem that Makefile.PL is not OK.

TIA,

Rich
