Nothing working seems to be available. So I recommend
to use f2py2e, http://cens.ioc.ee/projects/f2py2e/

*GEHRD are not too complicated at first glance,
so this will be pretty straightforward with the good documentation.
Give it a try and if you get stuck send me the status+files
(off-list) and I can have a look.
I think it would be great if
we can get more and more routines of this type included in scipy
by user contributions...

Best,

Arnd
