Jaro,
(cc grass5)

LOCATION is deprecated to allow for parallel sessions.
See
 http://grass.itc.it/pipermail/grass5/2002-March/002417.html

All scripts have been updated accordingly. I also updated
the g3.createwind and friends recently, perhaps that's
not yet in the CVS snapshot.

You can easily update
cd grasssrc
cvs login
PW: grass
cvs up -dP

Then recompile. There is no need to delete code locally,
just upgrade as above.

The trick to update scripts is: Add on top:
eval `g.gisenv`
: ${GISBASE?} ${GISDBASE?} ${LOCATION_NAME?} ${MAPSET?}
LOCATION=$GISDBASE/$LOCATION_NAME/$MAPSET

The $LOCATION must be constructed inside the script now.

Note: For PERL scripts I do not have a cool codepiece yet.
Only a workaround to simulate the "eval" function from shell scripts
in PERL scripts (help desired).

I assume that the problem is elsewhere since no longer hardcoded
library names should be used (portability). This is defined
by "configure".

I'll check that since I also have troubles to compile it.

More soon,
