Porting with Guix

[rennes]

Hi, I'm helping to port some applications to Hurd, with Guix package 
manager.
I am using Debian GNU/Hurd to perform my tests.

I have the following error when running the Screen application, and 
tried to debug as follows:

$ screen /home/buzz/.guix-profile/bin/bash
[screen is terminating]

$ gdb screen /home/buzz/.guix-profile/bin/bash
"/home/buzz/.guix-profile/bin/bash" is not a core dump: File format not 
recognized
(gdb) r

Any ideas to follow?

And thanks for the Hurd.
