cherokee-admin works, as it's been patched to use python2.

However, cherokee-admin-launcher does indeed need to be fixed to use python2. I'll fix that tomorrow. :)

problems remains:

$ cherokee-admin
env: python: No such file or directory
ERROR: Couldn't find python.

I'm unable to reproduce the issue you're describing. Please post the output of the following command:

$ pacman -Ql cherokee | xargs grep python 2>/dev/null | grep bin | grep usr

Sorry for late answer, I hadn't time to do check it out. Now here you are:

$ pacman -Ql cherokee | xargs grep python 2>/dev/null | grep usr | grep bin
/usr/bin/CTK-run:#!/usr/bin/env python2
/usr/bin/CTK-run:# -*- Mode: python; coding: utf-8 -*-

Binary file /usr/sbin/cherokee-admin matches <---------- This fails, but it's binary! May be hardcoded line the sources?

/usr/share/cherokee/admin/upgrade_config.py:#!/usr/bin/env python2
/usr/share/doc/cherokee/cookbook_dbslayer.html:<pre><tt>#!/usr/bin/env python

I checked the sources and my assumption was correct. Look into sourcecode

cherokee/main_admin.c:499:
char *const args[] = {"env", "python", "-c", "raise SystemExit", NULL};

I'll make a patch and give it a try.

Here is a new PKGBUILD with a patch. I'm asking if I could commit such bugfixes to repository by myself?

Nice find, it's starting to make sense now. I had Python 3 installed on the two machines I tested, and that made the check succeed.

Thanks for the patch and updated PKGBUILD. I chose to use a sed command in the PKGBUILD, which does the same thing. If you can confirm that the bug is resolved in cherokee-1.0.14-2, which I just pushed to [community], I'll go ahead and close this bug report.

Regarding your last question, only TUs have commit access to the repository and push access to [community].

In fact I don't understand why you would want using sed instead of patch in such cases, but it is not important, the point is, it should work :)
I think you can close this bug report now, thank you for your help.
