`Pkg.build("PyCall")` results in

Mac OS Sierra 10.12.6, and a freshly installed Julia\> VERSION v"0.6.0".  
Errors are very similar when attempting to build `PyPlot` and `Homebrew`;  
only the package name and line number change. I can’t tell from the  
error message what file is missing. FWIW: I’ve been upgrading Julia  
since around v.3x and have never encountered installation problems.  
This problem started after uninstalling JuliaPro and attempting to start  
anew with the standard installation procedure. Perhaps I didn’t uninstall cleanly.

`julia> ENV` produces
