 On {{{darwin9-powerpc}}}, building
 {{{py27-matplotlib at 2.1.0_0+cairo+ghostscript+gtk2+latex+qt4}}} failed with
 a GCC error message complaining about a for-scope declaration in
 {{{src/_macosx.m}}}.

 I have extended the existing {{{files/patch-src-macosx.m.diff}}} with one
 more hunk fixing that. As a result, {{{py27-matplotlib}}} builds with
 {{{gcc-4.2}}}.
