The Class::MOP and Sub::Name dll's are different beasts.
If they do not load, (even windows refuses to load them apparently)
you'll have to recompile them, followed by a perlrebase.

You have to exclude all mingw dll's from rebaseall.
This will be fixed in the next rebase package.

Either no write+exec permission or broken dependency.

If it's not the perm (unlikely), check the imagebase of your new dll:

$ cat ~/bin/imagebase
#!/bin/sh
objdump -p $1 |grep ImageBase |cut -c12-

$ imagebase /usr/lib/perl5/site_perl/5.10/i686-cygwin/auto/Class/MOP/MOP.dll
66c00000

And check the bases of the dependant dll's also: Anything below
0x4000_0000 is broken.
