We debugged this a bit further with Elias in personal email, and it
seems to be related to PATH differences.  The error message was that
'env' cannot find 'python' in the toplevel shebang line of the
hgwebdir.cgi script.  This shows exactly the same error in a test
script:

    $ ls -ld foo.py
    -rwxr-xr-x  1 keramida  users  43 Jan 25 11:33 foo.py

    $ cat -n foo.py
         1	 #!/usr/bin/env python
         2
         3	 print 'Hello world'

    $ env PATH=/bin:/sbin:/usr/bin:/usr/sbin ./foo.py
    env: python: No such file or directory

    $ env PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin ./foo.py
    Hello world

So indeed this is a bug that makes the apache onerestart script depend
on the runtime value of PATH to load everything correctly.
