Kallithea (waitress) not starting

Question

I made Kallithea's installation (into virtualenv) according to official guide. Then, I got following error:

(metal)1:17:46 root@dervish mercurial paster serve my.ini

PS: Only few options was touched in config. P.P.S: This secrion in config (my.ini) unclear for me:

[server:main]
## PASTE ##
# use = egg:Paste #http
## nr of worker threads to spawn
threadpool_workers = 3
## max request before thread respawn
threadpool_max_requests = 10
## option to use threads of process
use_threadpool = true

## WAITRESS ##
use = egg:waitress#main
## number of worker threads
threads = 5
## MAX BODY SIZE 100GB
max_request_body_size = 107374182400
## use poll instead of select, fixes fd limits, may not work on old
## windows systems.
#asyncore_use_poll = True

I tried to comment out use = egg:Paste with no luck.

This section allows you to select an HTTP server to use and to specify its options. You can select (use =) only one at a time, and you need to specify only those options it understands (they're different for different HTTP servers). So choose one and configure just it, comment out the rest.
