+On Ubuntu 8.10, if using the cvs source code rather than

+Answer:
+-------
+
+This is related to a compatibility problem between the shipped
+config/ltmain.sh and the libtool version installed on your
+Ubuntu 8.10 machine.
+You have to replace the config/ltmain.sh from cvs head by the one
+from your libtool package, make some cleaning and reissue all
+the build process:
+==========
+cd <your_lxc_working_dir>
+cp -f /usr/share/libtool/config/ltmain.sh config/
+rm -f libtool
+./bootstrap && ./configure && make && sudo make install
