 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:
 Keywords:  elcapitan       |       Port:  py38-pyobjc
----------------------------+-------------------------
 Attempting to upgrade py38-pyobjc after a selfupdate fails during
 building. Steps to reproduce:
 {{{
 sudo port clean py38-pyobjc
 sudo port upgrade py38-pyobjc
 }}}
 The main.log shows the following command failed:
 {{{
 :info:build subprocess.CalledProcessError: Command
 '['/opt/local/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8',
 '-m', 'build', '--wheel', '--no-isolation', '--outdir',

 }}}

 If I cd into the directory and attempt to run the build --wheel command by
 hand I get the following output:
 {{{
 /opt/local/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8
 -m build --wheel --no-isolation --outdir
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_macports_release_tarballs_ports_python_py-pyobjc/py38-pyobjc/work

 .org_macports_release_tarballs_ports_python_py-
 pyobjc/py38-pyobjc/work/pyobjc-9.0.1 does not appear to be a Python
 project: no pyproject.toml or setup.py
 }}}

 By the way I get the same failure to build with py39-pyobjc and
 py310-pyobjc. In fact the macports buildbot doesn't report success on any
 version of pyobjc on El Capitan.
