Yeah, and right after I wrote this e-mail I realized that there's
something fishy about this, because dependencies are not checked using
port names but using files in the FS; so devel/svk should realize
devel/subversion was built with perl bindings even if I did that by
myself.

I need more coffee I guess, this is not an issue if the ports work
properly. Sorry for the noise!
