Additionally, Perl 5.12 has been installed. This can be tested using /usr/bin/perl5.12; if there are no problems, it will become the default perl shortly.
Some modules are not currently available for Perl 5.12, such as RRDTool and Graphviz. These will become available before the default is changed.
My two Main-Perl Scripts had problems with the mysql-connect after your update. I think they cannot find the package DBI or have a problem with the new version.
For example see this error: http://toolserver.org/~sk/cgi-bin/checkwiki/checkwiki.cgi?project=gdwiki&...
Please check this.
Thanks for your update.
