OK, I managed to get through all the Java VM hooplah. I tried installing LimeWire again, and it detected the Java VM, but then I got a bunch of errors similar to this:

dirname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
/bin/ls: error while loading shared libraries: librt.so.1: cannot open shared object file: No such file or directory
basename: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
dirname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
basename: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
hostname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

Launching installer...

rm: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
rm: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

Anyone else come across this problem?
