the old homepage redirects successfully to the new one: HOMEPAGE="http://dockapps.org/file.php/id/158" the old SRC_URI has an INVALID redirect (to a spam page). As new SRC_URI I suggest: SRC_URI="http://dockapps.org/download.php/id/213/${P}.tar.gz"
The whole dockapps.org seems to be erroring out today... I'll wait and check again later.
dockapps.org seems to be gone permanently now. For abandoned dockapps like wmcp, I suggest using http://web.cs.mun.ca/~gstarkes/wmaker/dockapps/ for new HOMEPAGE and SRC_URI.
Back. Sorry for my (lack of) activity. It seems dockapps.org is back and well alive. Changed SRC_URI to working dockapps.org one. Not that this is all that important since the package tarball is mirrored on Gentoo servers anyway.
