bart and I are coming to the same conclusion. Oddly enough, the last ppd I can find for Devel::Build is .08 and according to the changes file, it ported to Module::Build at .09 version. Oddly enough, the test report shows the current version building on Win32 when MVC++ is used as the compiler. This leads me to believe it is a ActiveState/MinGW/Module::Build problem. I have several different makes lying around so that isn't the problem as I see the behavior with all of them.

Interestingly enough, my <make> test passed. Apparently a lot of the failing tests are marked TODO. As far as Devel::Caller::Perl, the particular module I am trying to install won't accept it as a surrogate dependency.

Thanks so much for figuring out a work around!!!! Any suggestions on who to contact on a real fix would be appreciated.
