Was your grass compiled under RH8 and then you upgraded? If so, you may
need to rebuild..

I did a fresh install of RedHat 9 yesterday on a new machine,  along
with a fresh install of Grass 5.0.2. Everything worked, including NVIZ.

Had to download fftw-2.1.5 source and compile, add /usr/local/lib to 
/etc/ld.so.conf, and run ldconfig first. (for FFT functions)

next, the following need to be installed, beyond the generic workstation
+ development packages:

RH 9.0 reqs:
use "rpm -q PACKAGE" to test, then "rpm -Uvh PACKAGE-1.2.3-4.i386.rpm"
to install.. 

postgresql 
postgresql-odbc 
postgresql-server 
postgresql-devel
unixODBC 
unixODBC-devel
lesstif 
lesstif-devel
blas
lapack
readline
libjpeg
libjpeg-devel
libtiff 
libtiff-devel 
libpng 
libpng-devel 
#gd     get v2.0.x from rawhide.redhat.com
#gd-devel 
tk 
XFree86-Mesa-libGL
XFree86-Mesa-libGLU
XFree86-devel
gdbm-devel 
postfix 
freetype-devel 

(most of those should already be there)


finally, build with
(replace pentium4 with athlon etc..)

CFLAGS="-O3 -march=pentium4 -Wall" LDFLAGS="-s" ./configure \
        --with-postgres-includes=/usr/include/pgsql/server \
        --with-motif \
        --with-motif-includes=/usr/X11R6/LessTif/Motif1.2/include/ \
        --with-motif-libs=/usr/X11R6/LessTif/Motif1.2/lib/ \
        --with-blas \
        --with-lapack \
        --with-glw \
        --with-dbm \
        --with-dbm-includes=/usr/include/gdbm \
        --with-freetype \
        --with-freetype-includes=/usr/include/freetype2
#        --with-readline \
make
make install

need cludge to get readline working. Run config without, then do
http://article.gmane.org/gmane.comp.gis.grass.user/1000
before make



hope that helps,
