I've looked at this message for a bit but can't do much further diagnosis
than the following - it's complaining about failing to load the shared
library (dll, dylib, ...) redland library from inside ruby.

I can't tell exactly what the problem could be here.  Could be
that your system shared library path (LD_LIBRARY_PATH etc.)
isn't including wherever librdf.so and friends got installed in.
In that case you might need to ./configure --prefix=/usr --with-ruby
then make, make install and retry.
