Comment:

 This is because the `conflicts` keyword deals with conflicts at activation
 time, for situations like when two ports install the same files (e.g.
 graphviz and graphviz-devel); it does not deal with conflicts at build
 time, such as qt4-mac's problem building when libevent is active. MacPorts
 base needs a new keyword to model build-time conflicts, and to reduce
 confusion the existing `conflicts` keyword might need to be renamed as
 well.
