[gnutls-help] Guile bindings not built due to "'guile-snarf' from Guile not found'

[Kenan Toker]

To all who read this:

This ended up being a Homebrew problem. I was able to build GnuTLS from
source without Homebrew in the way, and it installed fine.

If you need to make GnuTLS play nice with Homebrew, use `brew link'. NB
you need to install GnuTLS in /usr/local/Cellar to do this - see the
--prefix and --sysconfdir flags below.

    ./configure --enable-guile --with-guile-site-dir=no
    --disable-dependency-tracking --disable-silent-rules
    --prefix=/usr/local/Cellar/gnutls/3.6.9
    --sysconfdir=/usr/local/etc/gnutls
    --with-default-trust-store-file=/usr/local/etc/openssl/cert.pem
    --disable-heartbeat-support --with-p11-kit
    make
    make install
    brew link gnutls

Cheers,
Kenan
