About running PerlPad with a customized Perl installation
Can I use PerlPad with Perl 5.8.0 or 5.6.1?
Some people like to install another (newer or customized) version of Perl
in addition to the one supplied by Apple. PerlPad uses the CamelBones framework
to interface with the original Perl version. This code is highly dependent on a specific Perl version and compile-time options, so that it will only work with three Perl versions that come with 10.2, 10.3 and 10.4.
Unless you have actually deleted the system Perl (highly discouraged!), you should be fine. PerlPad will ignore your custom Perl version, and use the original one.
If you really need PerlPad to use an alternative Perl version, please check the CamelBones documentation.
