It shouldn't be necessary. People have used pre2 on MacOSX.

I should probably elaborate on my previous message.

In pre2 and earlier, the monitor socket is created in a subdirectory
of the current mapset, specifically:

	$GISDBASE/$LOCATION_NAME/$MAPSET/.tmp/<hostname>/<monitor name>

Eric changed this (after pre2) to use:

	/tmp/grass-<username>/<monitor name>

Other than the pathname used, the behaviour hasn't changed.

Basically, the directions given by Eric aren't applicable to pre2. But
check that the .tmp/<hostname> subdirectory exists. If it doesn't,
that would cause the bind() call to fail.
