I have got the log below during a sage build on OSX.
Shouldn't zlib be an order-only dependancy of pip ?
Found local metadata for pip-18.0

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the log file
/Applications/SageMath-8.6.app/Contents/Resources/sage/logs/pkgs/pip-18.0.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/Applications/SageMath-8.6.app/Contents/Resources/sage/local/var/tmp/sage/build/pip-18.0
and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
(cd
'/Applications/SageMath-8.6.app/Contents/Resources/sage/local/var/tmp/sage/build/pip-18.0'
&& '/Applications/SageMath-8.6.app/Contents/Resources/sage/sage' --sh)
When you are done debugging, you can type "exit" to leave the subshell.
