Re: devel/py-pyparsing and devel/py-packaging have circular dependency

Sorry, no, and please stop spreading this FUD and utter nonsense
about portmaster being at fault!

The error messages quoted by Iwao-san were obtained running a plain
"make" in both of the port directories.

In poudriere it does not. But it does when building the port on my
system with other Python ports already installed:

No portmaster involved, and devel/py-pyparsing definitely depends
on devel/py-packaging.

Apparently, both are BUILD_DEPENDS of each other, but apparently due
to some other Python package being present in the build environment.

I have 275 py38-* packages installed on my system, and I do not know how
to identify the one that adds the dependency on py-packaging.

And I have just rebuilt these 275 py39- packages on my system using
portmaster and this did not fix the issue.

I can build the packages with poudriere (and with my local version of
portmaster that supports building in a clean chroot jail), but not
directly on my system with lots of other packages installed.
