This is a classic symptom of putting USE_FOO into a Makefile with global
scope -- typically /etc/make.conf
Don't do that.
USE_FOO flags are for port maintainers to use in port specific
Makefiles. They do things like make the port have a dependency on
apache. Which is no good if you apply it to /every/ /single/ /port/ in
the tree, and particularly bad when its a port that apache itself
depends on, as you end up with a dependency loop.
Dependency loops are (in Ghostbusters parlance) like crossing the
streams. Anyone generating dependency loops deserves to be pelted with
stay-puft marshmallow, at the very least.
Instead, you want to use a WITH_FOO variable, or a WANT_FOO variable.
These are intended as user servicable parts. For apache, that would be
something like the following to make www/apache22 the default apache port:
WITH_APACHE2= yes
APACHE_PORT= www/apache22
Cheers,
Matthew
