For anything you want to compile from ports, just add:
WITH_OPENSSL_PORT= yes
to /etc/make.conf (or /usr/local/etc/poudriere.d/make.conf if you're
using poudriere)
Additionally you have to be careful of some ports that have GSSAPI
options -- don't enable GSSAPI support from the base system, or you'll
end up with a binary linked against two different versions of OpenSSL
libraries. Apart from that, the ports openssl is pretty much a drop-in
replacement.
For stuff you're compiling yourself, outside of ports, you need to force
your compilation to use the appropriate -I (for include files) and -L
(for libraries) search paths when compiling C code. How to do this is
specific to the compilation system used by whatever code your trying to
compile.
It's not feasible to remove openssl from base -- too much stuff in base
needs it -- nor is it feasible to overwrite the base openssl with the
ports version -- the ABIs have changed between the two versions.
I believe the ultimate plan is to make the base version of openssl a
private library and require all ported software to use the ports version
of openssl, but that is for future implementation.
Cheers,
Matthew
