Also, you will notice they never tell you to 'make install' so don't do it.
+On FreeBSD, the Makefiles are configured to
+locate the compiled openh323 port, if it has
+been built. Here is one way to build
+openh323 and ptlib on such that the Makefiles
+find it:
+ # cd /usr/ports/net/openh323
+ # make
+It is not necessary to install the port. The
+asterisk makefiles do not use any files
+installed by the port.
