the second example appears to the naive (like me) to be a super-set of the first example.

You want: (:or (:default "libc") "libc.so.6)

Also: (define-foreign-library libc (:unix (:or "libc.so.6")) (t (:default "libc"))) (use-foreign-library libc)

Doesn't work since OS-X is unix, but not linux. Maybe after failing on the specific case (i.e. unix), it could fall back to the general case?

I suppose falling back to other clauses in a COND-like fashion wouldn't hurt.
