I think it does work on Linux, but apparently not with whatever GL setup you have.  GL on Linux is a crapshoot beyond Nvidia drivers.

I do agree that vertex_ objects should not be built by default since there is still some 'discussion' about how they should work.

Ok, but if it only works on Apple, then shouldn't it be disabled by default on GNU/Linux?  Most ./configure build systems will build properly just given a ./configure && make   I think it would make for a lot less help emails to the list if Gem built automatically like that, then other features were enabled using the --enable- flags.
