It’s compiling… but not quite working. I get the same errors described in:

> [@MacOS Sierra (10.12.6) dynamic linker errors](https://discourse.slicer.org/t/macos-sierra-10-12-6-dynamic-linker-errors/2339):

> Hey guys, I’m running into some dynamic linker errors on startup with master built on 10.12.6: dlopen(/Users/hherhold/Development/slicer/build-qt5/Slicer-build/lib/Slicer-4.9/qt-loadable-modules/vtkSlicerCropVolumeModuleLogicPython.so, 2): no suitable image found. Did find: /Users/hherhold/Development/slicer/build-qt5/Slicer-build/lib/Slicer-4.9/qt-loadable-modules/./vtkSlicerCropVolumeModuleLogicPython.so: malformed mach-o: load commands size (32872) \> 32768 /Users/hherhold/Development/slic…

What I understand from this is that the initial pathname has to be short. How short does it need to be? I was compiling from /Users/michaelschumaker/Packages.
