Error: Processing of port rpm54 failed

Log contains:

checking for doxygen... no
configure: error: RPM API docs need doxygen in PATH

doxygen is typically a build dependency, not a runtime dependency.

Also it should be a port:-style dependency, not a bin:-style one. We don't want possibly old and/or broken doxygens the user might have installed elsewhere to satisfy the dependency; we want to use the MacPorts one that we more or less know will work.
