 The Portfile for VIPS is missing a dependency on swig. As a result, the
 Python binding is not built.

 Also, I wonder if the dependency on perl and p5-xml-parser should be
 depends_build rather than depends_lib? VIPS uses perl and swig at build
 time, but not at runtime. Though I'm extremely inexperienced with port and
 I'm probably wrong.

 I attach a modified Portfile that incorporates these changes.
