Can you tell me what you find in WPILibConfig.cmake and WPILibConfigVersion.cmake in /usr/powerpc-wrs-vxworks/share/WPILib/cmake, and check that any variables set in there are correct?

Well, that's an error in WPILib. <iostream.h> is non-standard and hasn't existed for some time - the compiler is right to throw an error there. Thanks for catching that - I've never included <WPILib.h> in my own code (and incidentally, neither does WPILib, as otherwise I would have caught the error earlier). For now just manually change it to <iostream>. The patch is in my github repo. I'm opening another bug on WPILib for all sorts of code that won't compile with a modern compiler - hopefully they listen this time...
Due to it being a pain to regenerate all the binaries no re-upload yet. Those who want the latest and greatest can as always grab it off github. Compiling WPILib is as simple as frcmake, make, make install.
