See summary. :) Tested stable on AMD64. I'd recommend altering the SRC_URI line from: SRC_URI="mirror://sourceforge/extace/extace-1.8.11.tar.gz" to SRC_URI="mirror://sourceforge/${P}/${PN}.tar.gz" so that a simple renaming of the ebuild provides the next version. Thanks!
Oh. Rereading this, I see that it should be: SRC_URI="mirror://sourceforge/${PN}/${P}.tar.gz" but you probably figured that out just by reading it.
In CVS. Portability update done on the old ebuild as well. Thank you for your report. If you wait two hours then sync, you will be able to merge the new extace.
