I think Joona's directions should get you going... I suspect that the
packged version of R for OpenSUSE isn't built with the
--enable-R-shlib flag, so it can't be used as a shared library.
Building from source should sort this out. If not, please do let me
know, and hopefully we can try to figure out something else.
