[clc-devel] Renaming core/pkgconfig to core/pkg-config

Hi, I'd like to rename core/pkgconfig to core/pkg-config, since the name of the package changed upstream (see http://pkg-config.freedesktop.org/wiki/). pkgconfig is currently listed in ~5 ports' dependency lists, so these could be easily updated. However, I think pkg-config should be treated as an essential package, since it's used by so many packages these days. That way, we could drop it from all of the depency lists ;) Any objections to renaming the port and removing it from any dependency list? Regards, Tilman
