+Subject: [PATCH] statically link with gnutls
+
+This requires libgnutls.a (and no .so) be installed in the ugly hardcoded
+lib dir. When built this way, the haskell gnutls library will link the
+library into executables with no further options.
+
+Also includes dependencies of libgnutls (needed since it's a static
+library).
