Hi all,
I'm working on fixing a `py-tensorflow` port issue
(https://trac.macports.org/ticket/55972) and I've found the following problem
when building `py-protobuf3`:
---> Building py36-protobuf3
Error: Failed to build py36-protobuf3: command execution failed
The log shows the following:
:info:build Executing: cd
"/opt/local/var/macports/build/_Users_enrico_repos_github_macports-ports_python_py-protobuf3/py36-protobuf3/work/protobuf-3.5.1/python"

The `py-absl` port is a new port that I've added while fixing this issue. The
`PKG-INFO` file referred to in the log message has the following permissions:
-rw-r----- 1 root wheel 889 Mar 23 10:04
/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/absl_py-0.1.11-py3.6.egg-info/PKG-INFO
I've verified that adding o+r to the permissions fixes the build issue:
chmod o+r
/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/absl_py-0.1.11-py3.6.egg-info/PKG-INFO
So far so good. The question now is: what's the best practice to fix _that_
file permissions in the `Portfile`? The `Portfile` is trivial, uses the
`python 1.0` port group and the installation is taken care of by `setuptools`.
Plus, I'm kind of a Python noob. Is this an installation issue which should be
fixed in any one of {upstream, setuptools, python port group, elsewhere}? Or
should I just fix the permissions in the `Portfile` by running `chmod`
manually? In the latter case, I've tried to guess what variables to use to
refer to that path on the `post-destroot` phase but I couldn't find the answer.
Thanks for you guidance,
