what's wrong with this is :

it's linking to the libraries in /usr/X11R6/lib intead of the older
versions in /usr/i486-linux-libc5/lib (I think. I've noticed that
re-linking to the other directory seems to fix this problem) . If you try
doing this : export LD_LIBRARY_PATH=/usr/i486-linux-libc5/lib
before you run it,
, it should work (quick hack...) . Also, I have /etc/ld.so.conf set up
like this:

/usr/i486-linuxaout/lib
/usr/i486-linux-libc/lib
/usr/X11R6/lib

I found that setting it up like this and running ldconfig, I didn't have
any problems with breakages.

If it says it can't find libc.so.5, it might be worth running ldd on it to
see what it does. Also, make sure you have the ld.so patch from
redhat. 

Actually, a better option is to install such extras in
/usr/local , where they won't interfere with anything in the RH
distribution (which puts everything under /usr). I have gimp 0.99.15 on my
system under /usr/local, as well as gtk. I also kept the gtk rpm from RH
5 (under /usr). everything works fine.
