Yes.

That's correct for Privoxy binaries for Windows but the same conflict
exists with LibreSSL.

The LibreSSL support is mainly useful for platforms like OpenBSD which
ship it as part of the base system so the "special exception" from
section 3 of the GPLv2 applies.

Do you have a libcrypto.so in the paths specified with the -L options?

Maybe you need to add another path (if you're still interested in building
with LibreSSL).
