Hold up right here. You read it wrong. This is for *makepkg* only, we
have *never* linked in anything external for pacman proper. We are
currently using code from XySSL as our md5sum routine, which is dual
licensed under BSD and GPL.

I do not believe calling a binary has ever been construed as linking-
correct me if I am wrong.

With that said, the rest of your email is pretty much off base.

Wrong ML is what I think about this. We don't decide Arch policy here,
only discuss pacman development.

Thanks! And if you have any more questions about this, shoot us another email.
