Sadly, the time profiling features of nhc98 have not been maintained
properly since the student who wrote them moved on.  It looks like a
change in the internal library structure in 1.16 has broken something.

It may be possible to rectify if you study src/prelude/Makefile
carefully and check that all the current libraries are mentioned in
the section beginning:
    ifeq "${TPROF}" "z"
I suspect that "NHC.Internal" is missing - there may be others too.
If you find a fix, send in the patch.

Yup, good point.
