this does not matter

like i said, you linked the wrong library, try to link
the right one. again, if you run the ldso under strace
the problem will be obvious and we dont have to waste time.
you should also strace ld to see what gets linked,
if it's /usr/lib/libcrypto... then that's wrong.
(instead of strace you can use -Wl,--trace)
