I tried to compile with the newest release of Eigen (3.1.0) and it didn't 
work and returned:

Returning to the alpha version compiled without errors. BTW, in order to 
switch between the version I edited "include_directories (BEFORE 
"~/Library/eigen3.1.0/")" in the CMakeLists.txt file.

How can I find out which compiler I use? How can I compile in debug etc.? I'd 
love to add any further needed piece of detail, but I'll need help finding 
it...
