Latest git commit (6e50d6f4430dc175f0e151891f5951d1322c2b5e) removed the savedconfig USE flag for the live ebuild. Please add it back, because upstream has it as well: http://git.suckless.org/dmenu/tree/config.def.h Actually it should be added to -4.6 version as well. Reproducible: Always
The versioned releases all have epatch_user instead.
