Latest version in tree: 0.9.5b Latest version available: 0.9.6b (more changes than the version number would suggest) Renaming the ebuild and copying in to PORTAGE_OVERLAY works.
Changing ebuild name to tkabber-0.9.6_beta.ebuild since that is the proper portage naming convention. FYI. Should be in shortly after I test.
tkabber-0.9.6_beta is now in ~x86 and ~alpha in portage. Thanks Michael.
