Comment (by ciserlohn@…):

 Replying to [comment:8 c.herbig@…]:
 > OpenBabel does not //require// wxWidgets unless the cmake -DBUILD_GUI=ON
 is set.  See [http://open-
 babel.readthedocs.org/en/latest/Installation/install.html#compiling-open-
 babel compiling open babel].  In the current portfile it is specifically
 set to off.  Meanwhile the only reference the portfile (or the eigen
 dependency) has to pkgconfig is in this line:
 > {{{
 > depends_lib         path:lib/pkgconfig/cairo.pc:cairo port:libiconv
 port:libxml2 port:zlib
 > }}}

 The problem is that OpenBabel uses pkgconfig to find cairo. Have a look at
 http://sourceforge.net/p/openbabel/code/5041/tree/openbabel/tags/openbabel-2-3-2/cmake/modules/FindCairo.cmake.
 Therefore OpenBabel must declare a dependency on pkgconfig like this:
 {{{
 depends_build port:pkgconfig
 }}}
