A followup:
After using 'g.setproj' in the source location (for r.proj) to define
the map datum, r.proj works fine.

Means: we need a change in case no map datum is present in the
PROJ_INFO file (which will be the case for many locations out there,
especially since the definition of a map datum is not forced).
