When installing mixmaster, the Install script can find
Looking for libcrypto.a...
Found at /usr/lib/libcrypto.so.
Compiling with OpenSSL 0.9.6e.
but the Makefile is written in a wrong way:

`/usr/lib/libcrypto.a', needed by `mix'. Stop.
the Install script should handle libcrypto in the same
way of libz if shared libraries found.
Also the Makefile generated lacks of the -O2 option.
