Sorry, if I was unclear.

As I sit behind a firewall, I have no access to PPM packages. So I made most modules by myself, including DBD::DB2, Tk and others. So, I consider myself being able to compile XS extensions. The perl Makefile.PL tells me about the dependent modules, if they are not installed.

The main problem is, that it does not seem to be as easy as to exchange the call to gettimeofday() with something functional equivalent, like _ftime(). My try did not change the external behaviour of Devel::Cover::get_elapsed(), that was easy to do without knowledge of Devel::Cover internals. But afterwards all tests failed, but only if not run through the debugger. The README says, there is debugger support, so that should not be the problem.
