Hi! grip-2.98.3 is a broken package version. We currently have media-sound/grip-2.98.3.ebuild and media-sound/grip-2.98.3-r1.ebuild in portage. I upgraded to grip-2.98.5.ebuild, and wanted to package mask the 2.98.3 versions (previous versions <2.98.3 are ok also) to avoid multiple "grip crashes on me" messages on gentoo-user (so we could get "how do I merge grip-2.98.3-r1 when I get a package mask error," instead :) Tried =media-sound/grip-2.98.3* in package.mask, but it didn't seem to catch grip-2.98.3-r1. It would be nice if a glob character would catch -r* versions. I have just added a line in package mask for both 2.98.3 and 2.98.3-r1 for now.
fixed on CVS. Will roll this into a new release soon. Thanks :)
