Hi Pierre and Evan,
This seems to be a red herring, as Guix does not change how CFFI loa > libraries. The only thing that changes is where the libraries are

I don't know about the details of SBCL and its CFFI, but there is a
difference in how Guix handles shared libraries that I discovered
recently and which might be related.
Programs compiled under Guix don't use the search path feature for
shared libraries (via Guix' own copy of ldd.so). All references to
shared libraries use the full path to the store. So if you compile sbcl
under Guix, it will never look for libraries that are referenced by name
only (without the full path). The foreign distro probably relies on that
lookup, as most Linux distros do.
Note that this is a feature, not a bug, so if that's the cause of the
problem, there is nothing to do about it. You'd have to compile sbcl
with the toolchain of the foreign distro.
Cheers,
Konrad.
