I was having trouble using sysutils/syslog-ng with self-signed
	ssl certificates after I installed the security/openssl port.

	I tracked this down to syslog-ng trying to open a rootca
	cert via a hash name, e.g. .../certs/9624bd1a.0, which didn't
	exist. When I first installed the openssl port I had noticed
	that the cert filename has changed and that it was necessary
	to re-run the c_rehash script against my certs directory.

	Since I had WITH_OPENSSL_PORT=yes in /etc/make.conf and had
	selected the PORTS_SSL option when building sysutils/syslog-ng,
	I suspected syslog-ng was linking against the base libcrypto.

	As it turns out the syslog-ng package is a twisted maze of
	shared images, some linked against /usr/local/lib/libcrypto.so
	and some against /usr/lib/libcrypt.so.

How-To-Repeat:
- Add WITH_OPENSSL_PORT=yes to /etc/make.conf
	- Build and install security/openssl
	- Build and isntall sysutils/syslog-ng with PORTS_SSL
	- Temporarily rename /lib/libcrypto.so.6 to /lib/libcrypto.so.6-
	- Create a syslog-ng.conf that uses tls() to forward logs:

	    destination d_syslog {
		    tcp("logger.noname.net" port(12345)
			tls(ca_dir("/usr/local/etc/certs")
			    key_file("/usr/local/etc/private/ahost.noname.net.key")
			    cert_file("/usr/local/etc/certs/ahost.noname.net.pem")
			    peer_verify(required-trusted)
			)
		    );
	    };

	- Attempt to start syslog-ng and see lots of shared images
	  that to reference the wrong libcrypto:

	    Error opening plugin module; module='afsocket-tls', error='Shared object "libcrypto.so.6" not found, required by "libafsocket-tls.so"'
	    Error opening plugin module; module='afmongodb', error='Shared object "libcrypto.so.6" not found, required by "libafmongodb.so"'
	    Error opening plugin module; module='afsocket', error='Shared object "libcrypto.so.6" not found, required by "libafsocket.so"'
	    Error opening plugin module; module='cryptofuncs', error='Shared object "libcrypto.so.6" not found, required by "libcryptofuncs.so"'
	    Error parsing afsocket, inner-dest plugin tls not found in /usr/local/etc/syslog-ng.conf at line 56, column 6:

			tls(ca_dir("/usr/local/etc/stunnel/certs")

Fix:
A minimal fix is to add -L/usr/local/lib where OPENSSL_LIBS
	is set in Makefile. However I believe the correct fix is
	something similar to the attached patch to bsd.openssl.mk
	which adds -L to OPENSSL_LDFLAGS. This approach should solve
	this issue for any port using this variable.
