I have GDE 2.2 running under a Redhat 4.0ish release with kernel 2.0.29.
Basically I recompiled it myself. Your problem is that the binary
is in aout format andyour system is almost certainly using elf. The only
to get it to use elf libraries is to recompile it. However this is a
pain, and
at least one of the programs is in fortran which will mean you'll have
to sort
out installing g77.

Very likely the library you are missing was called /libX11.so.3
The lack of any other path information before the name is significant.
You can
get around the error by making a symbolic link from /libX11.so.3 to
you are keeping the aout library eg:
 ln -s usr/i486-linuxaout/lib/libX11.so.3.1.0 /libX11.so.3
or you try some of these things.
The locations searched for libraries are /lib /usr/lib and directories
listed in
/etc/ld.so.conf. Mine looks like this:
cat > /etc/ld.so.conf<<EOF
After editing this file you have to update the cache by running as root
ldconfig -v
Including the i486-linuxaout directory might help - however I'm not
certain that
this is used for aout libraries. It might only be for ELF libs.
The environment variable LD_LIBRARY_PATH is used with the older
libraries, so possibly you could fix up a gde script like this:

/usr/local/bin/gde-2.2 $*

This would reset the lirary search path for gde and not mess it up for
any other program.
