Bugzilla Bug 132296

In portage, when you try to emerge gksu and don't have gtk-doc installed, you
get this (last few lines):
  gtkdoc-scan --module=gksu --source-dir=../ --ignore-headers="defines.h
pixmaps.h config.h"

/bin/sh: gtkdoc-scan: command not found

make[2]: *** [scan-build.stamp] Error 127

make[2]: Leaving directory `/var/tmp/portage/gksu-1.0.5/work/gksu-1.0.5/docs'

make[1]: *** [all-recursive] Error 1

!!! ERROR: x11-libs/gksu-1.0.5 failed.

!!! If you need support, post the topmost build error, NOT this status message.

Emerging gtk-doc first seems to fix this, but shouldn't gksu depend on it if
it's required for building? (USE="-doc", which I tried on a whim, didn't help
either.)

Thanks Mike - added dev-util/gtk-doc dependency to gksu-1.0.5.

I probably should stablise a later version soon as 1.0.5 is over 2 years old.

Just realized that gtk-doc installed a few other dependencies also, so that may
not be where it came from. But if you fixed it, who cares ;)
