Good catch !!!

Thanks for getting to the bottom of this.  Possible cause is the pkgsrc
config state is messed up.  I get to the end of the configure script run
using

  env PKG_CONFIG_PATH=/usr/pkg/lib/pkgconfig ../30.0.91/configure

and make completes. I'll next time try harder to read the config.log

On the pretest announcement the keyserver pgp.mit.edu works where
keys.openpgp.org fails for verifying the sigfile, btw.
