Which "ldd" did you use?  Ubuntu's or Guix'?
Where did you run it?

My only guess is what Konrad said: the libcurl library references its
dependencies with relative path (which ldd does _not_ display) and the
Guix loaded knows nothing about /usr/lib/x86_64-linux-gnu.

Try exporting LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu in the
environment in which you run SBCL.
