Description Juergen Rose 2018-08-02 17:54:23 UTC

'emerge -pvuDN simplecv' fails with:


root@lynx:/root(25)# emerge -pvuDN simplecv

These are the packages that would be merged, in order:

Calculating dependencies... done!

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by dev-python/simplecv-1.3::gentoo
# required by simplecv (argument)
>=dev-python/ipython-5.5.0 -python_targets_python3_6



If I add '>=dev-python/ipython-5.5.0 -python_targets_python3_6' to package.use,
'emerge -pvuDN simplecv' fails with:
...
root@lynx:/root(27)# emerge -pvuDN simplecv

These are the packages that would be merged, in order:

After masking >=dev-python/ipython-5.5.0 the issue disappeared.

This doesn't seem related to simplecv at all.  I'm going to guess it's actually a dupe of your other bug #662664 as I'm unable to reproduce it.
