Comment (by guano):

 I'm facing similar issues. Compiling on OSX 10.14 Mojave, with python
 3.7.4 (pyenv). I'm not using the Mac SDK, just the Mac Command Line Tools.
 Compilation breaks with this error:


 {{{
 Errors in:

 In case of errors please change into the directory with error and run
 'make'.
 If you get multiple errors, you need to deal with them in the order they
 appear in the error log. If you get an error building a library, you will
 also get errors from anything which uses the library.

 So I cd into ctypes and run make:

 {{{

 So is this NVIZ-related?
