Comment 0 for bug 1293169

Build of inkscape-0.48.x r10017 fails when building in MacPorts using recently released Xcode 5.1. This effects both OS X 10.8 (Mountain Lion) and 10.9 (Mavericks). Build is successful using previous version Xcode 5.0.2.

Build of trunk (r13156) and standalone lib2geom (r10017) are not effected.

Fails as follow:
