Based on http://forums.gentoo.org/viewtopic-p-5079556.html#5079556 using
MAKEOPTS="-j2" or MAKEOPTS="-j1" works on my system. I don't have others to
test on, but this suggests to me that it's a problem when using more processes
than cores. I also don't know enough about how ebuilds work to be able to offer
a fix.

missing docbook-xml-dtd 4.1.2 in DEPEND, well fix it in a moment.

and fixed.
