- Lookup for crypto functions in libcrypto instead of libssl. Some systems
(Mac OS) do not provide libssl, and the other have crypto functions in
libcrypto but libssl is dynamically linked against libcrypto:
% ldd /usr/lib/libssl.so
/usr/lib/libssl.so:
libcrypto.so.6 => /lib/libcrypto.so.6 (0x800c00000)
libc.so.7 => /lib/libc.so.7 (0x800647000)
- Do not explicitly link against libssl (instead of libcrypto BTW): the
autotools magic already does this at some point;
- Improve error message when headers cannot be found.
