Installation on gentoo using dorsal

Question

Hello

I am trying to install on gentoo using dorsal. On my gentoo the default python is 3.2.3 so I set the variable

PYTHON_EXECUTABLE=python2.7

So dorsal starts off and is trying to install Trilinos but fails with this error

Processing enabled package: PyTrilinos (Libs)
-- Found PythonInterp: python2.7 (Required is at least version "2.2") 
-- Python version 2.7.5

It looks like there is confusion with python versions since it seems to have found libpython3.3.so instead of libpython2.7.so. Any idea how to make this work ?

Thanks

You must also set PYTHON_INCLUDE_DIR and PYTHON_LIBRARY (see FEniCS/packages/trilinos.package).
