The other thing that might be wrong, if (require 'sb-bsd-sockets) is
failing but (require 'sb-cltl2) does not, is that sbcl executes tests
for its contributed modules and refuses to install those modules that
don't pass their tests.  Given the relative newness of Lion, it's not
impossible that something causes the tests for sb-bsd-sockets to fail,
which would make (require 'sb-bsd-sockets) give that error.  Assuming
that sbcl was built and installed without significant customization,
that would show up as 
  ls -ld /usr/local/lib/sbcl/sb-bsd-sockets
giving an error message.

(if neither Helmut's suggestion nor mine resolves the issue, I think it
would be necessary to see more detail about how the user has installed
SBCL.)

Cheers,
