[Slackbuilds-users] sbotools: multiline build options

[J. Milgram]

OK, makes sense, thanks.

Now for the problem that led to the question:

I'm getting an error upgrading python3-setuptools-opt. Per advice, 
ignoring the build options.

The  build attempt goes roughly like this:

==========
:~: sudo /usr/sbin/sboupgrade python3-setuptools-opt

CHECKSUMS.md5.asc verified. See /usr/sbo/gpg.log.

...

Setuptools is a fully-featured, actively-maintained, and stable
library designed to facilitate packaging Python projects.

Installs to /opt/python$PYVER/site-packages.

...

It looks like python3-setuptools-opt has options; would you like to set
any when the slackbuild is run? [n]

Proceed with python3-setuptools-opt? [y]
setuptools-80.10.2/
setuptools-80.10.2/LICENSE
setuptools-80.10.2/MANIFEST.in

...  < unpacks many files, applies patches > ...

File 
"/usr/lib64/python3.9/site-packages/importlib_metadata/_itertools.py", 
line 16, in unique_everseen
    k = key(element)
AttributeError: 'PathDistribution' object has no attribute 
'_normalized_name'

ERROR Backend subprocess exited when trying to invoke 
get_requires_for_build_sdist

===========

For quite a while I suspected it had to do with the PYTHONPATH build 
option but that now seems not to be the case.

So I'm guessing I have a package version mismatch of some sort, but 
can't figure out what it might be.

Does anyone recognize this error? Any tips on running it to ground? FWIW 
this is an up-to-date Slack64-15.0 system. Some SBo's are a minor number 
or two behind but I'm already running into SBo packages that fail to 
upgrade because sbotools tries first to upgrade python3-setuptools-opt, 
which build fails.

grateful for any ideas!
