MIB compile error

I try to add a mib as i can't find raid traps already complied for 2400 server in MIB.BIN for monitoring individual drieves in the raidset .Using Dell's MiB's recent downloaded I get this:

C:\WINNT\system32>mibcc -n -o OUT.BIN SMI.MIB arymgr.mib
Microsoft (R) SNMP MIB Compiler Version 2.00
Copyright (c) Microsoft Corporation 1998. All rights res
mibcc: parsing smi.mib
SYNTAX ERROR on line: 9, Last token read is "internet"
Err [mibcc.cpp:194] - CheckSyntax() failed!

Any trick ?
