The OP should keep an eye on dependencies, though.  A good foot-shooter 
is updating one port, and then, during updating a different port having 
to install a newer version of a port they both depend on.

Which might require a rebuild of the original port, resulting in having, 
at best, double-downtime of a service.

Incidentially, I ran into this just right now, so I felt compelled to 
state what might seem obious :)

PS: I seem to remember devel/pcre being a good candidate for that with 
postfix and some other ports.
