a new version of spamprobe was released some days ago. The new ebuild now does not need my patch of the last version, because they changed their db detection themself now :). I tested building with this dbs: 3.2.9-r10 4.0.14-r3 4.1.25_p1-r3 4.2.52_p2 I had no problem this time, on all of my systems. Attached the new (simple) ebuild. Reproducible: Always Steps to Reproduce:
Created attachment 42426 [details] New ebuild
Ebuild (with some modification) added to CVS portage, thanks for reporting. It should be hitting mirrors in few hours.
