I have tested successfully with the following command on a foreign
system:

  guix environment --ad-hoc automake pkg-config guile guix libgcrypt sqlite 
guile-sqlite3

Tell me if it works for you.

It would indeed be nice to provide an easy way for Guix users to install
Cuirass.  IMHO package definitions meant as a development build tool is
confusing and should be avoided.  Nonetheless, I think it is useful to
document the previous 'guix environment ...' command in the README.

Thank you for your feedback.
