Transmission 2.41 was released at 2012/02/14. Thanks in advance! Reproducible: Always
I'm sorry, on previous comment have the wrong version. The correct version is 2.50.
Tried the trick of simple renaming the ebuild but then it does not find the matching patchset. Disabling the patchset in the ebuild produces a compilefail with natpmp. Renaming the patchset in the distfiles too and it fails to apply the 01_all_configure.ac.patch. So we need a matching patchset. Seems I have to give up. Life is not always easy.
