This little thing was added to portage one or two days ago, but I can't understand why it wasn't added the latest version instead of 0.0.5. Just renaming the ebuild will work, but you also need to fix the URI a bit like this: # diff -U3 /var/portage/kde-misc/smaragd/smaragd-0.0.5.ebuild /var/portage/local/kde-misc/smaragd/smaragd-0.0.7.ebuild --- /var/portage/kde-misc/smaragd/smaragd-0.0.5.ebuild 2011-08-15 15:27:50.000000000 +0200 +++ /var/portage/local/kde-misc/smaragd/smaragd-0.0.7.ebuild 2011-08-15 23:48:13.096765605 +0200 @@ -9,7 +9,7 @@ DESCRIPTION="KWin theme engine that uses Emerald themes" HOMEPAGE="http://kde-look.org/content/show.php?content=125162" -SRC_URI="http://www.kde-look.org/CONTENT/content-files/125162-${P}.tar.bz2" +SRC_URI="http://www.kde-look.org/CONTENT/content-files/125162-${P}.tar.gz" LICENSE="GPL-2"
By the way, this has nothing to do, but while you are at it, you might want to move this from kde-misc to x11-themes, like gtk-engines-* or the crystal kwin decoration. I don't want to open another bug just for that but if you want I can do it.
Both done, thanks.
