Comment 8 for bug 900354

(only for Debian Squeeze with manually built Wt 3.2.1, Ubuntu Lucid will be latter)

I have tried "g++ 900354.cpp -o 900354 -lwt -lwthttp" -- the same result:

/usr/bin/ld: /tmp/ccB6Voar.o: undefined reference to symbol 'boost::signals::trackable::~trackable()'
/usr/bin/ld: note: 'boost::signals::trackable::~trackable()' is defined in DSO /usr/lib/libboost_signals.so.1.42.0 so try adding it to the linker command line
