*sigh*  Well, we now use pkg-config for finding dependencies; I've
updated my Ubuntu colo VM from Oneiric to Pangolin, to get libgnutls28
available.  libgnutls28 remains non-default, but I have it now.

There are now two -dev packages containing headers and the pkg-config
file, "libgnutls-dev" and "libgnutls28-dev".  They're marked as
conflicting, so only one can be installed at once.

So Exim's current limitations concerning conflicts in include/library
paths for different components aren't an issue.  Install the -dev
package wanted, use USE_GNUTLS_PC=gnutls as suggested in Local/Makefile
and anyone building for themselves will get GnuTLS 3.
