This is not real error message. It just means that something else failed.

Here is the relevant part of the traceback from the linked email:

File "/tmp/pip-build-env-7rsifsqj/overlay/lib/python3.9/site-packages/pyqtbuild/builder.py", line 67, in apply_user_defaults
  raise PyProjectOptionException('qmake',

Here is that line in pyqtbuild/builder.py source code:

https://riverbankcomputing.com/hg/PyQt-builder/file/1.13.0/pyqtbuild/builder.py#l67

And it means that PyQt-builder was not able to find qmake in PATH. You should
add qmake to PATH or pass a custom path to sip-build using --qmake option.

There is nothing specific to ppc64le in our packaging.
