Actually I've gotten it to work this way, with real(8) in the wrappers.

BUT... for some reason it requires me to set the environment variable  
G77='gfortran -fdefault-real-8'. Simply putting it in f2py_options='-- 
f77flags=\'-fdefault-real-8\' --f90flags=\'-fdefault-real-8\'' doesn't  
seem to do the trick. I don't really understand why.
