I would:
1. Upgrade Trac to 1.2.2. Make sure to read TracUpgrade.
http://trac.edgewall.org/wiki/TracUpgrade
2. Review your Apache configuration against the recommendations on the 
TracModWSGI page.
https://trac.edgewall.org/wiki/TracModWSGI

I do not use virtualenvs, and I saw that post you linked, not the same 
situation. He is showing an old python version with a new hmac file. I am 
showing a new python version with a new hmac file and it is only 
randomly(1/50) not finding the dependency.

Search the web for "_compare_digest". It seems you might have an old 
virtualenv or a second old Python installation somewhere or something 
like that. For example:

0.11.7 is very, very old. It's unlikely this is the cause of this 
problem, but you should still upgrade.

We will probably need to see your Apache configuration file.
Which Trac version are you running?
