Perl's DBI Module on OS X - uninstallable?

i've been struggling with installing the Perl DBI & DBD modules all weekend, and I'm getting close, but no cigar as of yet. When I run the perl script db.pl I get the following mismatch error:

Mon Apr 19 09:43:29 EDT 2010 
/Library/Perl/DBD-mysql-4.011 ->
peterv@MBP17.local<515>$: db.pl | tee ~/DBI_Mismatch.log
DBI object version 1.609 does not match $DBI::VERSION 1.608 at /opt/local/lib/perl5/5.10.1/darwin-multi-2level/DynaLoader.pm line 227.
BEGIN failed--compilation aborted at /opt/local/lib/perl5/site_perl/5.10.1/darwin-multi-2level/DBI.pm line 263.
Compilation failed in require at /Users/peterv/Perl1/db.pl line 7.
BEGIN failed--compilation aborted at /Users/peterv/Perl1/db.pl line 7.

I've obviously installed 2 versions of the DBI module, and during compilation the source and objects became mismatched. I'd like help with 2 questions:

  1. Do I have to uninstall the DBI modules currently installed? (I would guess yes.)

  2. How can I uninstall them? (I've found many articles on the web about how to install them, but none on how to uninstall them.)

I'd be very grateful for any advice.
