Bug 311469 – app-eselect/eselect-python: python-wrapper: Print error message when python is not found

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Fabian Groffen 2010-03-26 16:45:23 UTC]

situation:
- emerged new python (2.6)
- portage died right after unmerging the existing version
- system left in a state without python-2.6

what happens:
% python
% echo $?
127
%

Ok, it could be a lot more helpful if it would shout at stderr here that no python is found.

% eselect python list
Available Python interpreters:
  [1]   python2.4
  [2]   python2.5

nothing is selected any more of course, but the wrapper still is there and in the first place it hides that there is a major problem.

Got the same problem on a old installation updated today:

Looks like python-2.6.4-r1 ebuild does not report SLOT='2.6' correctly...

# emerge -1 python:2.6
