I installed this from a binary package. I think the issue is that the host that built the binpkg has: # eselect python show python3.2 While the host that tries to install the package has: # eselect python show python2.7 How this leads to the quoted error, I don't know. But I assume that this is an issue with the Python eclasses. Likely to be treecleaned as it's no longer maintained and neither has eapi5 support That binpkg certainly looks like the cause of the problem. As pkgcore is not yet capable of EAPI 5. We'll hold off any binkpg verification changes until that's done and working. This is a code problem with py3.2+:
# pquery --debug
Cannot load script pquery.

The above exception was the direct cause of the following exception:

script = modules.load_module('pkgcore.scripts.%s' % (name,))

snakeoil.modules.FailedImport: Failed importing target 'pkgcore.scripts.pquery': ''has_conditionals' in __slots__ conflicts with class variable'
Closing as obsolete since pkgcore has never officially supported py3 yet and current ebuilds in the tree reinforce that. |
