That error has recently started occurring with the latest versions of
GCC. The issue is fixed in the current CVS version.

Either update the r.terraflow code to the CVS HEAD version, or use an
older version of GCC for compiling r.terraflow.

Or just manually remove the template parameters from the destructor
prototypes, i.e.:
