OpenID login for wiki (and using HG from source)

[anatoly techtonik]

I again find absent login with GMail for wiki as a showstopper.

In particular, this page:
http://mercurial.selenic.com/wiki/DebuggingFeatures
Lacks info how to run 'hg' from source to use standard Python
debugging aids (like `trace` and `pdb`) to troubleshoot problems with
HG or its extensions (I currently investigate issue "ValueError:
invalid literal for int() with base 16: 'logi'" between hg, hg-git and
dulwich).
