 I can't say what exactly installed {{{Mono.framework}}} at the moment -- I
 have several things installed that might have done it, like
 {{{Steam.app}}}.

 It was not obvious to me with 5 minutes looking how to make
 {{{supertux}}}} ignore {{{Mono.framework}}} so I disabled it for the
 {{{supertux}}} build, and that worked around the issue, although -
 obviously - not a proper solution to it.

 cmake can set certain include directories as system directories to be
 searched before other system directories. I would imagine that adding the
 {{{freetype2}}} include path to that "search before system list" might be
 a way.
