Here's a second version of the patch. I needed to conditionally define
the PKG_PROG_PKG_CONFIG macro since that's no available on old RHEL-4.
Second, I had to make make gnutls fallback to doing a AC_LIB/AC_HEADER
check if pkg-config fails because ancient gnutls doesn't have pkgconfig
support. Finally I also had to add another compatability define for
the gnutls_cipher_algorithm_t typedef.
With this all done, it now works correctly on both RHEL-4 and my F8
boxes.
Regards,
Dan.
