I don't know about compatibility between SLES and OpenSuse or whether 
you're able to install 3rd party rpms, but:

I don't think you need these packages if you're compiling and installing 
wxWidgets yourself. wxGTK should have everything you need in it.

Sorry, this error isn't familiar to me. But I was a bit surprised that 
your self-built version looks to be in /usr/lib - I would have expected 
it to be in /usr/local/lib or /opt/lib. Might be worth checking again 
what wx-config --libs returns, and that the wxRuby build is pointing to 
the right libs.

Perhaps you might post the first few lines returned when running 'rake' 
to build wxRuby, summarising the kind of build to be done and the 
classes that will be excluded (eg PrinterDC is always skipped on Linux).

I can find a few references to this error message on the web with 
wxWidgets and various other packages and software, but no decisive solution.

The fact that the error is occurring with GCDC makes me wonder if the 
problem is specific to that class. Did you build wxWidgets with 
--enable-graphics_ctx? If you didn't, you might try this - especially if 
rake is not reporting that support for GCDC, GraphicsContext etc is 
going to be skipped.
