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.

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.
