It looks like the MIME::Lite module is still trying to read in the MIME::Types code, despite your setting of that flag. It could be that MIME::Lite needs the code in some other capacity, or it could be an oversight on the part of the MIME::Lite developer.

What I recommend you do is send e-mail to the maintainer of MIME::Lite, to point out this problem. But in the short-term, just to get your own work back on a forward-moving track, I recommend installing MIME::Types from CPAN.
