All you need are the xotcl tgz and the tcl thread extension from there for:
1. XoTcl you do
./configure --prefix=${AOLSERVER_INST_DIR} --enable-threads --without-tk --without-gdbm
--with-tcl=${AOLSERVER_INST_DIR}/lib
make
make install-aol
2. For thread you do in unix sub folder:
./configure --enable-threads --with-aolserver=$AOLSERVER --prefix=$AOLSERVER --exec-prefix=$AOLSERVER
make
cp libthread2.6.1.so ${AOLSERVER_INST_DIR}/bin
3. Finally you add this to the config file:
ns_param thread ${bindir}/libthread.so
That's it.
Thanks to Patrick Rebscher for figuring that out.
