Hello, thank you for this great distro, my daily driver for over two years!
After a recent upgrade, the evince and qpdfview packages will no longer open .eps (postscript) files. This is a recent change - I have regularly used these packages to open .eps files for years.
It appears that these packages (and two others) have been compiled with the postscript USE flag off:
$ eix --installed-without-use postscript [I] app-text/evince [I] app-text/qpdfview [I] media-gfx/gimp [I] media-gfx/imagemagick
Please re-compile them all with this flag on…
