You only need to change that one line. The logic below is a bit
complicated because it will use PETSc (if available), otherwise
Trilinos (if available). The order is reversed if you uncomment the
line above.

Timo -- I think what confused the reporter was that the comment says "uncomment the following #define", but there is just an #if and a complicated one to boot. Maybe ought to update the comment -- I think I recall the #if having become significantly more complicated recently.
