Before the build I performed make clean & make clean_plugins & configure. Must I install some additional libraries to build the CL on Ubuntu 9.10 now?
Indeed, you are right its a bug in the configure script.
The missing symbols are implemented in C files (not C++), however the configure only collect .cpp files for that shared library, fixed in local svn, will test and commit it later
