In this case, the configure script skips the call to pkg-config if
$libssl_CFLAGS is set.  I was able to get a successful build by passing
the proper environment variables to configure without the need for
patching it.  This is what I added to the ports Makefile:

.if ${SSL_DEFAULT} == base
. if ${OPSYS} == FreeBSD && ${OSVERSION} < 1000000
IGNORE=	base OpenSSL in FreeBSD 9 is too old, specify a ports version of SSL by adding DEFAULT_VERSIONS+=ssl=... to /etc/make.conf and rebuild everything that needs SSL
. else
		libcrypto_LIBS="-L${OPENSSLLIB} -lcrypto"	\
		libssl_CFLAGS="-I${OPENSSLINC}"			\
		libssl_LIBS="-L${OPENSSLLIB} -lssl"
. endif
