Please use the same setup as the MacPorts Portfile [1]: local tests on OS X 10.7.5 confirm that using the configure option '--disable-strict-build' allows to compile inkscape trunk r12320 (state of latest inkscape-devel portfile) outside the MacPorts tree without failure, with the latest versions of glib, glibmm and gtkmm as currently patched and installed via MacPorts (see comment #2). Without that configure option, compiling trunk fails as reported.
