error building sage-10.7 on mac

[mhampton]

Hi,

I am getting an error building sage-10.7 on an intel mac, the problem happens in building the contourpy-1.3.1 package.  It looks like this is a somewhat common issue, because of some versioning issue with pybind/ninja/meson tools.  I am attaching the log file for the contourpy package.  

This commit seems relevant: https://github.com/contourpy/contourpy/pull/498/

but I am not sure how to apply it correctly to sage-10.7.

Any help appreciated,

Marshall Hampton

Hi,
probably, your toolchain is too new for 10.7.
Could you try the git, develop branch, or (a bit older)
https://github.com/sagemath/sage/releases/tag/10.8.rc1 ?

I tried building 10.8.rc1, it almost got there but died compiling numpy.  I am attaching the log.
