Hi,

try:

GRASS> g.version -r

:)

GRASS> echo $GISBASE
GRASS> echo $GRASS_LD_LIBRARY_PATH 
GRASS> ls $GISBASE/lib
GRASS> echo $LD_LIBRARY_PATH

that should show you where the grass install is located.

It's usually fine to have many versions of GRASS installed
at the same time, they can all run self-contained.

--> you might check if the 6.4.2 install is listed in /etc/ld.so.conf
or /etc/ld.so.conf.d/*, if so change it to the location of the 6.4.3
libraries and re-run `ldconfig` (as root).


good luck,
Hamish
