How can I test whether this works as expected?  I tried this, but I=E2=80=
=99m
unsure whether it=E2=80=99s supposed to load OpenSSL=E2=80=99s libssl.so di=
rectly or
not:

Apologies in advance if I=E2=80=99m just asking stupid questions!

Besides, it would be nice to get rid of these hard-coded /usr/local in a
subsequent patch.
