The data of the funcs-file (an MFA) is compiled into the MIB, so you only
have to make sure that your node has the path to the module implementing
the functions referenced in the funcs-file.

As stated by the documentation, you have to give the full path to the
MIB-file. You can put your MIB-files anywhere you like.

As I wrote in my previous mail, db_dir is just a place for the snmp
application to store internal data.
