Template:FAQ:MIBs 05

If this error is only generated for one or two modules, then it's likely that the named modules are not being found - perhaps they're not installed in the correct location, are not readable, or the name being used is incorrect. See the previous entries and the entry How do I add a MIB to the tools? for more details.

Note that the name reported is the name of the MIB module, which is not necessarily the same as the name of the file.

If there are a large number of such errors, then it's more likely that either the MIB files haven't been installed at all. If you are compiling from source, then it is necessary to run "make install" in order to set up the full run-time environment.

Otherwise, see the previous entry to check whether the MIBs are installed in the correct location for the tools to find them.
