I suspect that because of the changes to the new build and to PPM especially, that there are compatibility issues between the Packages. If I'm wrong, I'm certain someone will point it out.
I think you are right.I've been at this for ages thinking there was something wrong with my setup but what you say makes sense.
I would have saved myself a day if I knew that first..aw well:-)
Any modules I could not get I managed to download from CPAN and build myself using nmake.
