Added patch to fix gnutls includes detection during build. Move libiconv
dependency to the NLS option, which is what requires it. Setting DESTDIR
in INSTALL_ENV is superfluous - removing. Set PKGMANDIR via --mandir in
CONFIGURE_ARGS instead of passing PKGMANDIR in MAKE_ENV. Updated patch to
reflect change. Patches sent upstream. Disable gnutls option by default,
as it requires openssl compatibility, which is currently not supported in
pkgsrc. Bump PKGREVISION.
Reverting previous commit. wiz@ had it right.
