Bug 789699 – net-libs/libtorrent-rasterbar - Build fails with "ModuleNotFoundError: No module named 'setuptools'"

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description abbotta4 2021-05-12 15:32:28 UTC]

It looks like the ebuild does not include setuptools as a BDEPEND if the python USE is used

Reproducible: Always

Steps to Reproduce:
1. emerge net-libs/libtorrent-rasterbar-1.2.12
2. The build will fail with the title error in the log
Actual Results:  
The build fails to build libtorrent-rasterbar without the setuptools module

Expected Results:  
Portage should successfully build and install libtorrent-rasterbar

emerging dev-python/setuptools and rebuilding libtorrent-rasterbar yielded success

Yeah, we need to add the dependency.

>DISTUTILS_OPTIONAL=manual

means the eclass won't add any dependencies at all. ${PYTHON_DEPS} is needed which we use but you have to manually add setuptools too AFAIK based on how the eclass reads.

May be worth updating the eclass documentation as it's a bit confusing:
>If you enable DISTUTILS_OPTIONAL, you have to set proper dependencies for your package (using ${PYTHON_DEPS}) and to either call distutils-r1 default phase functions or call the build system manually.

Just wanted to report I've run into the same issue - have a system I've not updated in some time, encountered this when trying to update from 1.2.6 to 1.2.14.

I was unable to update dev-python/setuptools as suggested due to some dependency nastiness, so I resorted to unmerging this (libtorrent-rasterbar) package as well as the torrent client that depends on it to get my update world moving again.

In case this helps anyone else:
equery depends net-libs/libtorrent-rasterbar
emerge -ca [some bittorrent client as reported by equery]
emerge -ca net-libs/libtorrent-rasterbar
emerge -uUD world

I assume net-libs/libtorrent-rasterbar will build correctly once the rest of my system is up to date, as it did for abbotta4. If not I will report back.
