Any idea?

You need to first upgrade to a more recent version of FOX 1.4. The
compile error you're seeing is due to a bug in the FOX header files,
and this bug was fixed in FOX 1.4.12 (way back in April). Please
resist the urge to download FOX 1.6, since FXRuby 1.4 is not in fact
compatible with FOX 1.6.
