The Ubuntu Trilinos package is old (10.4). It is a modified  version,
because the 10.4 source fails to compile with gcc 4.6.

There is a nasty change in the Epetra interface - the old code still
compiled, but thanks to an interface change the code did something
different.

I would prefer to support just the latest (10.8). Is there demand for
10.4? I wouldn't advocate using any of the Ubuntu/Debian linear
algebra packages (Trilinos/PETSc/BLAS) for performance.
