Good catch. That approach won't be very robust when saving images.

It does on SBCL. Is it correct theoretically to call DEFCFUN from inside of IF?

Also, when somebody saves lisp image and the image opened next time, possibly different version of OpenSSL is loaded. The defcfun done before saving the image, will it conflict with the new library?

That solution looks interesting. Does it work?

foreign-symbol-pointer should work on Corman, yes.

If so, maybe this is the best solution?

(if (cffi:foreign-symbol-pointer "OpenSSL_version_num")
    (cffi:defcfun ("OpenSSL_version_num" ssleay) :long)
    (cffi:defcfun ("SSLeay" ssleay) :long))
