This is likely caused by the library being compiled as 64-bit. The "(null)" means that Mono was not able to obtain the error message of this error. You can fix this by setting the appropriate compile flags. For instance:

./configure CFLAGS="-O -arch i386" CXXFLAGS="-O -arch i386" LDFLAGS="-arch i386" --disable-dependency-tracking

You may also be able to fix this by using Mono's experimental 64-bit support but I have never done that so am not sure.
