To continue on this topic, I just found out that d.profile also exits with
the same error message. As I said earlier, grass was compiled using the
axptrick 64-bit port from Berkeley.

My lack of knowledge of the design of grass (and C programs to some degree)
makes my efforts to locate this bug very unsatisfactory, so I would still
appreciate assistance on this.

Best,
