Issue with kallithea 0.6.2 in combination with mercurial hook

[Mads Kiilerich]

If you can get the same error when launching your scripts manually 
without Kallithea, then the problem must be in your local system - not 
directly related to Kallithea.

Again, I can only advise against installing in /usr/local - it is very 
easy to get inconsistent installations, and very hard to clean up.

But also, I guess Kallithea should do something to ensure that we 
actually invoke the hg installed in a Kallithea virtualenv. You can do 
the same in your scripts.
