While installing a fresh gnome-2.18 (i.e. no upgrade) I ran into this problem
while compiling gnome-extra/gconf-editor-2.18.0:
[...]
make[2]: Leaving directory
`/var/tmp/portage/gnome-extra/gconf-editor-2.18.0/work/gconf-editor-2.18.0/po'
Making all in docs

/bin/sh: line 1: scrollkeeper-config: command not found
The file '/Templates/C/scrollkeeper_cl.xml' does not exist.
Please check your ScrollKeeper installation.

Installing app-text/scrollkeeper-0.3.14-r2 fixed the problem. I think there
should be a dep on scrollkeeper in gconf-editor?
(this is ppc64, but this should be a problem on all arches I think)
