It seems that LD_LIBRARY_PATH is defined in your
.bashrc or
.cshrc
(echo $SHELL to find out your shell). Edit the related file (.bashrc or
.cshrc or whatever) and add 
:/usr/lib:/usr/local/lib

to the setting of LD_LIBRARY_PATH. However it may be better to change it
to

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/matlab_r12/extern/lib/glnx86:...

Means: To have the original LD_LIBRARY_PATH included. Then start GRASS
in a new shell window, check  again
echo $LD_LIBRARY_PATH
and try.

Note that this is a local misconfiguration which is not related to GRASS.
Excluding /usr/lib and /usr/local/lib from LD_LIBRARY_PATH will also
cause problems for other programs.

If you cannot find and redefinition of LD_LIBRARY_PATH in your .bashrc
or .cshrc or whatever, ask your local admin to repair that.

Hope this helps,

 Markus
