Thank you for your help on this package.

According to the Cyrus SASL quickstart guide:

"Note that the library can use the environment variable SASL_PATH 
to locate the directory where the mechanisms are; this should be a 
colon-separated list of directories containing plugins."[1]

Unfortunately I still do not know enough about Guix packaging to 
set this environment variable properly, nor do I know how to 
properly set the installation path in the package configuration.

This plugin's build and installation instructions are:

./autogen.sh
./configure
sudo make install
