OK. To update guile I thought I would follow the guix README file and
build guix with guix.
So, I've given the command:

$ guix package --install={autoconf,automake,bzip2,gcc-toolchain,gettext,guile,libgcrypt,pkg-config,sqlite}

and got the packages installed :-)
At the end of the process I've been told to define the following
environment variables:

   export PKG_CONFIG_PATH="/home/beffa/.guix-profile/lib/pkgconfig"
   export ACLOCAL_PATH="/home/beffa/.guix-profile/share/aclocal"

On top of those I've defined the PATH as follows:

export PATH=$HOME/.guix-profile/bin:$PATH

The README file mentions all of the following veriables: ACLOCAL_PATH,
CPATH, LIBRARY_PATH, PKG_CONFIG_PATH. However, only the above ones
have been mentioned during the installation phase and defined.

Then I've cleaned up the build area with "make distclean" and
according to the README file I've issued

./configure --with-libgcrypt-prefix=$HOME/.guix-profile/

Unfortunately I've got a new error:

$ ./configure --with-libgcrypt-prefix=$HOME/.guix-profile/
checking for a BSD-compatible install... /usr/bin/install -c

configure: error: in `/home/beffa/Downloads/guix-0.7':

Please find attached the full config.log.

What do you think? Would I be better downloading and installing a
newer guile version the "traditional" way?

Thanks for your help!
