Weird problems building Scalar-List-Utils-1.18 on Win32+MinGW
The problem you are seeing on ActivePerl with Scalar-List-Utils is related to Module::Install pre 0.61 combined with a recent AS Perl (817 for sure, maybe earlier). I have reported the problem to the author, but he failed to release a new version with a more current Module::Install so far. See the corresponding RT ticket.
For now, the solution is to send a mail to the maintainer and then locally install Module::Install from CPAN, delete inc/ in the unpacked Scalar-List-Utils distribution directory, run Makefile.PL and voila, it 'make's.
