Hmm, can you give your ebuild of opensp and openjade? Who knows, may be ebuilds from my mirror differ from yours... I tried clang-3.3, gcc-4.6.3 and gcc-4.7.3 from stable branch and no success.

Also, I have this:
52) [1] nikita opensp >> equery g opensp

Is it a circular dependency? Emerge doesn't tell anything about this.

I have installed software exactly those versions mentioned above except automake-1.14 which is unstable.

Any time I see build errors in c++ programs I suspect libtool.
(No, I can't explain why, I just do ;)

For that reason I'd suggest running fix_libtool_files.sh, just
in case your gcc ebuild didn't do it automatically.

FWIW, opensp builds successfully for me and my configure logs
look very much like yours (I'm using gcc-4.8.2/~amd64, though.)
