In Python 3 print is a function, and should be called like this:
print('\n', s, '\n', '=' * len(s))
This works as-is in Python 2, unless you have this at the top of the
file:
from __future__ import print_function

Thanks Keith, that was suggested on the ceph list but grepping doesnt
show it in the source. With this version of ceph they have replaced the
ceph binary with a python script so its quite different from the older
version which works. They target mainly centos and ubuntu/debian so I
will have to keep looking.

Have you tried a simple:
python3 /usr/bin/ceph

No, doesnt work either. The ceph guys say it works fine for them which
leaves me suspecting something is broken on my system ...

Still not sure if I have a bug or a broken system.
1. If I use eselect to set python 3 and build ceph from the ebuild
it wont work
2. If I eselect python 2.7 it wont work
3. if I rebuild it with python 2.7 selected it now WORKS - yea!
4. if I eselect python 3.2 it wont work :(
Ok, I am suspecting that something in ceph isnt playing nicely with the
gentoo eselect system and having python2 and python3 on the system :(
I guess its pulling in something python2 when 3 is active which is where
the __future__ mechanism comes into play.
So next question is ... can I remove python2? - last I heard, portage
needs python2 and wont run properly with python3 - is that still the case?

[gentoo-user] ceph and a possible python problem
Iam trying to build the latest ceph (dumpling - 0.67, not in the tree) from tarball - it compiles/installs but when I try and run it I am getting: olympus ~ # ceph File /usr/bin/ceph, line 192 print '\n', s, '\n', '=' * len(s) ^ SyntaxError: invalid syntax olympus ~ # The ceph irc people thought it might be the python version, but Ive tried both python2 and python3 I am now back on the older 61.7 which works fine - any ideas? Even if someone else is successfully running 0.67 would be useful information (i.e., its my problem :) BillK
