It's great that you've sent a solution, but it's not very pretty. As it is,
I would consider SSL functionality broken and would put a big warning on the
SSL howto page.

I'll probably make a custom ebuild for gentoo with a patch, however most
folks are using binary packages and will probably have issue with this

Care to post a unified diff?
