Description qeldroma 2009-09-24 17:34:55 UTC
Emerging v1.9.45 works, but this one, unfortunately a direct dependency for kde-4.3.1-printing is not compiling.

Perhaps i'll have to mention that i am trying to build a bleeding edge kde-4.3.1-system with a lot of unmasked ebuilds..

I checked the symlink, it's ok:
# ls -l /usr/bin/python*
lrwxrwxrwx 1 root root    9 24. Sep 18:51 /usr/bin/python -> python2.6
lrwxrwxrwx 1 root root    9 24. Sep 12:17 /usr/bin/python2 -> python2.6
-rwxr-xr-x 1 root root 5352 24. Sep 10:10 /usr/bin/python2.6
lrwxrwxrwx 1 root root   17 24. Sep 12:17 /usr/bin/python-config -> python-config-2.6
-rwxr-xr-x 1 root root 1200 24. Sep 10:10 /usr/bin/python-config-2.6
-rwxr-xr-x 1 root root 9520 24. Sep 10:09 /usr/bin/python-wrapper

Reproducible: Always

Steps to Reproduce:
emerge it

Actual Results:  
fails

Expected Results:  
emerge works ;)

 # emerge pycups

It's obviously incorrect. /usr/bin/python must be a symlink to python-wrapper.
You should run e.g.: eselect python set python2.6
Comment 2 zvasylvv 2009-10-15 08:19:34 UTC
I got same error ('/usr/bin/python' isn't valid symlink) while tried to update a setuptools. IMHO this error does not depend on package. I guess it happens after user updated a python (ie 2.5->2.6). After emerge has been finished, some amount of recommendation is shown. One of them says that run of python-updater is highly required. Its sets /usr/bin/python symlink to /usr/bin/python2.6, while correct value is python-wrapper.

Could maintainers of python check this test case?
Comment 3 edoceo 2009-10-25 15:57:32 UTC
I saw this issue today as well, while upgrading a dev-python/pycrypto.
I wish the error message was more, clear and maybe pointed me to `eselect`

However, when I ran `eselect python list` it showed I had 2.6 selected
lithium / # eselect python list
Available python interpreters:
  [1]   python2.4
  [2]   python2.6 *

As a symlink to 2.6 not to python-wrapper
lithium / # stat /usr/bin/python
  File: `/usr/bin/python' -> `python2.6'

Then I simply re-selected 2.6 and all was well
lithium / # eselect python set python2.6
lithium / # stat /usr/bin/python
  File: `/usr/bin/python' -> `python-wrapper'

None of the updates (for python, pycrypto or eselect) told me to do this in their emerge/ebuild outputs.
Comment 4 Decibels 2009-11-21 23:44:25 UTC
reselecting python 2.6 worked for me even though already had it selected and was the only one to select. Was emerging 'sip' when got this error.
