Admin issue, quite a common one too.

see ports/Mk/bsd.openssl.mk
they have both the base system ssl at play and the ports version.

in this day in age you almost always want everything against the port
b/c of CVEs and timelyness.

WITH_OPENSSL_PORT=yes
in /etc/make.conf or other appropriate places will trigger the port.

Its so low in the dependency chain, that I'd recommend you re-install
all ports on the box to relink them all correctly.
