I've synched up the MacPerl sources with perforce and CVS, including only one core patch (to disable SA_RESTART for singal handling, in util.c).
So for 5.6.1r2, I have left to clean up the docs, build Shuck 1.7.0 (which has some really nice new additions, along with some significant improvements and bug fixes in parsing and rendering of the POD text), release new versions of a few of my modules (e.g., Mac::Glue) with recent modifications, and that's about it.
