That solved it! This one should be in the manual under debugging :)

It ended up being a problem with the python egg cache. I ended up adding:
if 'root' in cache:
    
os.environ['PYTHON_EGG_CACHE']=os.path.expanduser("~nagios")+"/.python-eggs"
     pkg_resources.cleanup_resources()
     pkg_resources.set_extraction_path(os.environ['PYTHON_EGG_CACHE'])
     pkg_resources.cleanup_resources()

This solved the problem.

Thanks for helping me solve this one. I've been scratching my head for
quite some time.

Tarjei
