ActiveState updated Perl Dev Kit (PDK) to 7.1, to add support for Perl 5.10 (in addition to the 5.6 and 5.8 support).
PDK is the essential tool suite for Perl developers that facilitates the creation and deployment of professional Perl applications.
Some other issues were also addresssed, like adding support for Mac OS X 10.5.  You can read all the details, try the Perl Dev Kit.
It is of course a free update for existing PDK 7 users.
