Version 0.5 of svninfo is out (http://www.brucker.ch/projects/svninfo/index.en.html). Although I have managed to install this package manually, I have not been able to adapt the existing ebuild (version 0.21) to install version 0.5 correctly. Could somebody help, pretty please? I'm willing to act as tester; I'm on amd64 (not that it matters, I don't think).
It has been bumped to 0.5 in CVS. The things that needed to be changed were the SRC_URI (which now happily points to upstream tarball) and the svninfo-0.2.1-latex-compile.patch needed to be slightly edited as a bug has been corrected. Thanks for reporting.
