Would you care to send me a copy? Most of my development machines at work run on NT Workstation with ActiveState. It would be nice to know what's going on in advance. (just checked ActiveState's site and came up with zero).

Updated too:
Ok, so it seems this applies to 5.6 only. I have found a few odd features in the past with activestate (this binmode unpack was a new one though). We are currently using build 522 (5.005_03), so the above doesn't really apply. Nevertheless, I'm going to give Dynamic Perl a shot. I'm dropping the "better the devil you know" philosofy for a new chance at getting something more stable.
