Hi Daniela,
Have you tried './pre-inst-env guix build ...' instead of 'guix build
...'?
The difference is that the former command will look for package
definitions in your checked out, and modified, version of Guix.
The latter command looks for package definitions in your installed

Hi Roel,

A 'guix pull' within your profile will update the guile-zlib version

Dear Paul,

Nice!
Trilinos has many bells and whistles. I imagine that there will be some
significant effort required to package it. One option would be to
subdivide the library and initially package only the elements you need
for Lethe.
Hi Guix,
I recently attempted to reproduce a profile containing emacs-auctex,

The reason is that elpa.gnu.org archives previous auctex versions with

definition, which expects a .tar extension.
