This is a package container for the mib files created by the mib2py compiler tool. Compiled-to-Python MIB files are placed in this namespace.
The latest set of pre-compiled mibs, installed separately, is available here:
After downloading the mib tarball file do the following:
mkdir -f /var/tmp/mibs
cd /var/tmp
tar xzf /path/to/pycopia_mibs.tar.gz
The package is coded to look there also for MIB modules.
