A new version of sane-backends with new drivers has been released Reproducible: Always Steps to Reproduce: 1. 2. 3.
I would like to have the brothermfc-patch included, but have to modifiy it first. Could take some time... if it's not done by the end of the week, I'll drop it and add it again later.
I've just tried the new ebuild: you should comment this section or it will request the patch: if use usb; then unpack ${BROTHERMFCDRIVER}.bz2 fi with this fix the backend builds without errors :)
-r1 has the patch again. Considering this fixed until further notice :-)
