On Mac OS X, type

file libgluegen-rt.jnilib

 or

otool -hv libgluegen-rt.jnilib

. You should see:

$ file libgluegen-rt.jnilib 
libgluegen-rt.jnilib: Mach-O 64-bit dynamically linked shared library x86_64

$ otool -hv libgluegen-rt.jnilib 
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00       DYLIB    12       1352   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS

If these show as 32-bit libs, then you'd need to switch to a newer version of JOGL :)
