Something is really bad/weird with your setup.

From the above log, it looks as if (maybe) you have gcc installed, and the compilation of XML::Parser::Expat somewhat succeeded, but you can't load the DLLs.

This might be some weird group policies that prevent you(r programs, like Perl) from loading DLLs or maybe you don't have the appropriate DLLs. How did you (try to) install XML::Parser::Expat? And/or how did you install your current Perl? If you can restore from backup or install a really fresh Perl while wiping out all traces of this current state, my suggestion is that you do so.
