As a Python user, this looks really cool, thanks!

As a packager, is the libmpdec library used elsewhere? For Gentoo, we
generally prefer to package libraries separately and have Python
depend on them. From the site, it seems like you more or less wrote
libmpdec for usage in Python, but if it's general-purpose and actually
used in other software, it would be nice if Python grew a configure
option to make it use the system libmpdec.

Cheers,

Dirkjan
