Oh, oh! I don't even know what a "Via C3" is, outside of what I just read on Google. Appears to be x86 compatible, so it "shouldn't" be a problem. What are the symptoms? What OS are we talking about? Have you (can you?) tried the old-fashioned "make install" approach?
I can notify the development team (if I get some more information), or you can file a bug report yourself. Sorry you had a problem with it. Thanks for the feedback!
Best,
Frank
