libgeodecomp-0.4.0 fails to compile

[HJarausch]

I'm working on a Gentoo system.
I have libflatarray-0.3.0 installed here.
Compilation of ibgeodecomp-0.4.0 fails here with several errors, e.g.

/var/tmp/portage/sci-libs/libgeodecomp-0.4.0/work/libgeodecomp-0.4.0/src/testbed/performancetests/main.cpp:2253:41:

Libgeodecomp 0.4.0 requires an older version of libflatarray. However, libgeodecomp bundles its own version of libflatarray. So if you un-emerge libflatarray everything should be fine.

This problem is fixed in gentoo now (see https://bugs.gentoo.org/681160). Bug can be closed.
