The install script won't work, but you can copy the files manually.
First, you'll need additional libraries: libXm.so.3 and
libstdc++.so.5. The libstdc++ library is available via apt-get.
# apt-get install libstdc++5
Put libXm.so.3 in /usr/lib.
Copy the contents of ctf.linux/bin from the installation iso into /opt/ctf/bin. The documentation and other things are optional.
