The simple answer is no...  I'm not sure if Linux has some magic to help out,
but on windows if the dll isn't there it won't load.  You can mess around with
delayed loading or if there were only a few exported functions you could load
them up at runtime (not the case here).

Every windows machine has openGL installed, how likely is it that a linux
machine doesn't?  Basically you have two choices - build a separate version
without 3d, or make openGL a dependency.  I've very limited linux packaging
knowledge, but I assume gnubg has lots of dependencies (gtk, cario, etc), can't
you just add one more?
