[syslog-ng] FreeBSD install with SSL

I have a FreeBSD system that has the SSL libraries not built from ports. Apparently the syslog-ng port expects ssl to be installed from ports. I'd prefer not to do that at this time. However, when building syslog-ng from source, it expects pkg-config (or gnome-config as this FreeBSD still refers to it) for SSL, which also is not going to work. I've not tried the balabit supplied FreeBSD package. Any guidance on the best approach to get syslog-ng with SSL support installed onto this FreeBSD box? Keep in mind I'd like to avoid changing the installed openssl libaries at this time. Will the balabit package do the trick? Perhaps it is better to modify the build process from source? John
