 Let's say we want to `sudo port install djview pidgin +no_x11+quartz`,
 they recursively depend on cairo +x11 and cairo +quartz+x11 respectively.

 cairo +x11 gets installed within djview installation
 {{{

 --->  Attempting to fetch cairo-1.12.16_1+x11.darwin_13.x86_64.tbz2 from

 }}}
 and then an error occurs within pidgin +no_x11+quartz installation because
 its dependency gtk2 depends on cairo +quartz
 {{{
 --->  Fetching archive for gtk2
 Error: org.macports.archivefetch for port gtk2 returned: cairo must be

 Error: Processing of port pidgin failed
 }}}

 Manually reinstalling cairo (and pango which fails next for the same
 reason) `sudo port install cairo +opengl+quartz pango +quartz` solves the
 issue.

 Can it be done automatically?

 P. S. Sorry if the bug is duplicate, searching on such an abstract topic
 is quite difficult.
