Current version in Portage is 0.9.7 (Sep 30 2006). Current version from upstream is 0.9.9 (Jan 04, 2010). Reproducible: Always Steps to Reproduce: Dependencies are listed here: http://etherape.sourceforge.net/download.shtml#requirements ...but I think (could be wrong) that they haven't changed. The new version seems to compile and run fine when I simply update version number of the ebuild in my own local overlay.
Thank you for report David. Fixed. BTW, the only missed dependency was - app-text/gnome-doc-utils. It was new in this version of etherape.
