I then generate a ruby file from the xml produced above using the 
ffi-swig-generator
project.
In the produced ruby I get signatures like:

attach_function :H5Sget_simple_extent_dims, [ :int, a().hsize_t, a().hsize_t ], 
:int
attach_function :H5Screate_simple, [ :int, a().q(const).hsize_t, 
a().q(const).hsize_t
], :int

I am a little lost for an explanation for the methods:
a().q(const).hsize_t
a().hsize_t

Is the source of these methods the permafrost project?

It seems the issue is with the ruby-ffi library.  This addresses comment #1.
The patch is still required.

A number of custom Swig typemaps are needed to move data in and out of the 
libjhdf
native code. Currently the typemap code only supports Java as a target 
language. 

Supporting multiple languages is a goal for the future. However, generating a
complete mapping of the C HDF API is not a small task: there are literally 
several
hundred functions and scores of data types. All of these must be mapped, 
documented
and tested. I simply do not have the resources to do two language mappings at 
once.

If you are interested in starting work on a branch for another language, please
contact me through gmail.

Sorry about the noise - after bumping around I worked out I could get quite far 
by
swig + ruby's ff-swig-generator project by haveing swig produc xmloutput from 
the raw
hdf headers.
Ironically less was more in this case - really just piggy backing off Ruby's 
swig
generator project.
Best wishes 
HH
