I'm using wxwindows 2.4.0 with GTK2 and Ruby 1.8.0.

My best guess is that wxRuby was compiled with a different version of
the C++ toolchain than your wxWindows library. Unfortunately, C++
binaries have traditionally been incompatible between versions of g++.
So you may need to compile wxWindows from source on your box, or you may
need to compile wxRuby with the same compiler that was used for your
copy of wxWindows (by manually modifying Makefile, I suppose).

In my case, I use g++ 3.3 because that is the Debian Sarge default.

We need to add this to the README and/or a FAQ.

Thanks,

Kevin
