Does this ebuild work better?

It does fix the same issue here.

[Comment 8 Matthias Maier 2015-12-12 06:16:37 UTC]

This issue is due to a check in the python.eclass:

347 _python_initial_sanity_checks() {                                                
[...]
349         # Ensure that /usr/bin/python and /usr/bin/python-config are valid.      
350         if [[ "$(readlink "${EPREFIX}/usr/bin/python")" != "python-wrapper" ]]; then
351             eerror "'${EPREFIX}/usr/bin/python' is not a valid symlink."         
[...]
361 }

and is also hit by other packages, for example media-libs/libkate that happens to have this innocent call in package_setup():

28 pkg_setup() {                                                                    
29     if use wxwidgets; then                                                       
30         python_set_active_version 2                                              
31         python_pkg_setup                                                         
32     fi                                                                           
33 }

I'd say this is a clear bug in the python.eclass, isn't it?

[Comment 9 Matthias Maier 2015-12-12 06:25:39 UTC]

For the record, I believe this is due to the following change in app-eselect/eselect-python:

commit f28f2e793b1639b91e2e47ba50886bf25d0d28d6
Author: Michał Górny <[e-mail]>
Date:   Wed Nov 25 13:35:51 2015 +0100

    app-eselect/eselect-python: Replace python{,2,3} symlinks with files
    
    Copy python-exec script to /usr/bin/python{,2,3} rather than symlinking
    it because a lot of Python scripts like to readlink(sys.executable) and
    don't expect to find python-exec in there...


CC'ing python herd. Shall we reassign the bug?

[Comment 10 Michał Górny 2015-12-12 07:05:58 UTC]

We could fix the old eclass (bleeeeh), or wait a bit more to see how many more old ebuilds people are using :-P.

Ick, so instead ignoring this type of bug in my tinderboxes I should rather file bugs as blocker of this ?

[Comment 12 Michał Górny 2015-12-12 11:11:35 UTC]

That won't really be helpful. I'm more curious how many packages are not used at all.

[Comment 13 Michał Górny 2015-12-12 13:00:43 UTC]

I've killed the check in python.eclass. Seems to work on my box.
