MAPGEN and GRASS

[Andrew Hertz]

Hi,

I have several MAPGEN/GRASS questions...

I just downloaded and installed GRASS4.1 and I noticed that
the mapgen and proj versions embedded within GRASS don't 
seem to match the most up to date stuff on charon.er.usgs.gov.
GRASS seems to be using mapgen version 4.0 and proj versions 3.1, 4.5, and 4.6.  On charon... is mapgen version 4.1 and proj
version 4.1.3.  Do you suggest getting the latest from charon
and using it in src.related.mapgen?  And can you explain the
three versions of proj in GRASS and what versions 4.5 and 4.6
correspond to?  

The next set of questions relate to the notorious GRASS/MAPGEN
makefile interfaces.  I believe I've gotten mapgen built under
GRASS 4.1, but there's an SCS subdirectory which I believe
contains additions/upgrades from the Soil Conservation Society
that is giving me fits (along with lots of their stuff in
src.contrib).  The only problem I had with make'ing the other
mapgen stuff is that it was expecting some directories to exist
that I had to manually create.  The directories were:
$GISBASE/mapgen/bin
               /gfonts
               /interface
               /man
               /xgen

Thanks,
Andrew Hertz
