Comment:

 The conflicts_build portgroup can be used to at least give users an error
 message that explains the problem and gives them a solution.

 Near the top of the portfile, put:

 {{{
 PortGroup conflicts_build 1.0
 }}}

 Then later, near the configure and build options, put:

 {{{
 conflicts_build-append ${name}
 }}}
