These drivers still require that you add the command line options to link properly with the native library.
Set your mtouch extra options to:
-gcc_flags "-L${ProjectDir} -lgebeprinter -force_load ${ProjectDir}/libgebeprinter.a"
At least one user has reported that you must also set LLVM armv6/armv7 support for the bindings to work. This will depend on which binaries the upstream provider is shipping.
