Linux Install Problem

Hello everyone:

I recently downloaded the linux version of grass4.1 and ran the
installation script with no problem. I am using the 0.99.13 linux kernel.
When I try to run grass using the command "grass4.1", I get the following
message:

/usr/grass/etc/lock: can't load dynamic limker '/lib/ld.so'
Unable to properly access /home/grass/.gislock
Please notify system personel.

I edited "grass4.1" to reflect my installation location as follows:

:
GISBASE= /usr/grass
export GISBASE
exec $GISBASE/etc/GIS.sh

I realize that there is a .gislock and .grassrc file tha tmus tbe located
in the user's home directory, but am unsure of what should be in them.

Can anyone be of assistance?

Thanks in adavnce....
