For me, the "stable" version 9.40 flat out won't build; instead, it goes into
a '/bin/sh: line 0: cd: gpacks/README: Not a directory' loop.  The requested
version --- 9.4.3 --- builds and installs, but a couple of its tests fail with
FEATURES=test enabled.  But in this case, I'll mark it stable, just to help
get rid of 9.40.  (Note that my system is x11-base/xorg-x11-7.0-r1.)
