I've been playing with the microsoft downloads of MS VC++ and have finally fiddled my way to compiling and installing DateTime (there isn't a PPM as one of the Infinate tests fails).
And, it wasn't so bad:
I installed three MS things: The full platform SDK (available as an ISO download), the free Visual C toolkit, and the dot net redistributable - although I'm not certain I really needed that.
Add in an ActiveState perl then perl Makefile.PL. Then edit the Makefile to use libcmt.lib rather than msvcrt.lib, and make, make install. All rather too simple...
There are DateTime modules in Randy Kobes PPM site.
