With regard to GRASS:

it's been my experience (under 2.1) that the problems with the GRASS
core (src, src.alpha) are minimal. I believe that I only had to make
about 3 minor changes to code last night to get it to compile the
update - there may have been more changes that I made earlier. Once
you fix one or two things, it becomes easy (i.e., you get the hang of
it; e.g., change index() to strchr()). It helps if you know from
experience what the differenes are between BSD and System V, but you
won't be handicapped if you have minimal knowledge of C and can read
man pages. BTW, this is *without* using any of the backward compatibility
features that Sun provides - I'm trying to wean myself in a hurry.
That's the general statement.

Personally, I've had problems with xgrass, but that could be my Motif
version (1.2.2) and/or my compiler (Sun's). I've never gotten it to
compile, but since we don't use it ...).

Another problem that may be unique to my site and/or digitizer 
is continuing problems with v.digit*. We could never get v.digit
to work, and v.digit2 is so incredibly slow that it is not useful.
The speed of our LX/Solaris 2.1 combo is sufficient for number
crunching, but I've found that any code that makes system calls
or reads from a serial port takes a tremendous hit. However,
I'm about to see what changed with the update, so hopefully
I'm speaking out of turn.

Just my 2 centavo.
