Oh right, I forgot this one.

Yes, it seems to be the case.  When using Guile from the host distro,
you must use guile-gnutls from the host distro as well.

Weird, did ./configure even pass?  You can run:

  ./configure --with-libgcrypt-prefix=/usr/whatever/

to make sure it picks libgcrypt.so from the host distro.
