As Jochen already wrote, the correct way to write an OID is without the leading dot. I know that CMU/UCD do it differently and many people took over that style. But that does not make it legal.

Anyway, recent versions of libsmi have a special function call you should use instead of smiGetNode() in this case:

extern SmiNode *smiGetNodeByOID(unsigned int oidlen, SmiSubid oid[]);

This API function makes a lookup based on an OID and it does not care about the MIB module which actually contains the definition.
