This is a bit of a long shot. We have a test failure for TAP::Parser 0.51 on Windows:
It's Perl 5.8.5 and to this (untutored) eye it looks as if it's not ActiveState's build. I've tried to build 5.8.5 here but can't get it to play nice with VC++ 8.0.
If anyone might happen to have 5.8.5 installed on a Windows box and could make test against both T::P 0.51 and a snapshot from the SVN and report back I'd be most grateful.
FWIW the tests all pass on Windows/5.8.8.
