You seem to be trying to link a dynamic swarm library from static versions 
of libobjc and hdf5.  The Cygwin linker does not like it.  Although the 
MacOS X linker would be perfectly happy.

The solution would appear to be to build libobjc and hdf5 as dynamic 
libraries or make the whole thing static (? not possible with Cygwin?)
