Here is the problem. A binary linked against libc.so.5 _and_
libc.so.6 cannot possibly work. The libc.so.6 is linked in because
your newly compiled X libs depend on it (they are created with gcc
-shared ... -lc), even though your netscape binary of course doesn't
depend on it.

This is offtopic for linux-kernel, but it will hit lots of people.
The solution is either get new binaries, or to keep the X11 libs for
libc-5 in a different place. The latest ld.so packages have support
for managing this situation.

Regards,
Wolfram.
