It turned out that the problem is actually while compiling sparse2d. At some point, cmake calls for a different compiler than the one we expect.
Solved by setting export DCMAKE_C_COMPILER=gcc. It was pointing to a /usr/bin/c++ which is a 4.8.5 gcc.

I won't close the issue now, as there is probably a minor bug in the installer that can be solved. I might look into that in the future.
