The rtai_sem module must be loaded. It has been many years since I tested
Orocos against RTAI/LXRT. Solving this will require typical debugging
skills such as analysing the last lines of 'dmesg', turning on the debug
features of the RTAI kernel modules, checking if the API of RTAI 3.5 -> 3.9
didn't change semantics (ie we check for a return value which was different
in 3.5 or 3.9)
Another thing you should do in RTT is :
cd build
cmake .. -DENABLE_TESTS=ON
make check
and report on which unit tests work and which don't.
Good luck,

this is the output of make check :
