So libcrypto and libssl now are symlinked to 0.9.6e?

	ldd /path/to/binary

tells what libraries a file uses.  If you see libssl and
libcrypto, it's dynamically linking to OpenSSL.

When something is statically linked to OpenSSL,

	strings /path/to/binary | grep OpenSSL

will tell you the version of OpenSSL (in addition to displaying
some other cruft).  This works for OpenSSL, but is not universal;
it works because OpenSSL stores the version number when compiled.
