I was stuck was my Xorg server refusing to start so after trying a few things I tries te re-emerge awesomeWM. Portage then proposed to add 

# required by x11-wm/awesome-3.4.15::gentoo
# required by awesome (argument)
>=media-libs/imlib2-1.4.7 png

to my package.use, which solved the problem after reinstalling imlib2 with this useflag.

If I try to comment the above line in package.use and try to reinstall imlib2, portage complains about awesome depending on imlib2 having png useflag

WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:

media-libs/imlib2:0

  (media-libs/imlib2-1.4.7:0/0::gentoo, ebuild scheduled for merge) conflicts with
    media-libs/imlib2[png] required by (x11-wm/awesome-3.4.15:0/0::gentoo, installed)


I therefore don't understand why it dropped the useflag in the first place

The dependency has been dropped in x11-wm/awesome-3.5.6 so in a world update containing update for awesome, the use flag was dropped, but as the emerge world did'nt get to awesome the old awesome was still in use
