Error Building cmake Port

[Tim Daneliuk]

Trying to build cmake and getting this, even though setuptools is installed:

Scanning dependencies of target documentation
[  5%] sphinx-build man: see Utilities/Sphinx/build-man.log
Traceback (most recent call last):
  File "/usr/local/bin/sphinx-build", line 6, in <module>
    from pkg_resources import load_entry_point
ModuleNotFoundError: No module named 'pkg_resources'
--- Utilities/Sphinx/doc_format_man ---
*** [Utilities/Sphinx/doc_format_man] Error code 1


This is on:  11.3-STABLE FreeBSD 11.3-STABLE #0 r351732


Anyone else encounter this and/or have a fix (I've tried reinstalling setuptools).
