Spectrum Support is not responsible for making corrections to mibs that are not owned by CA/Broadcom.
MIB Tools tries to point out warnings and errors as to why a mib will not compile.
When compiling a MIB within Spectrum, the client will parse all files within the folder where the MIB is located and this can sometimes cause unexpected results. You can create a new folder and place only the problem MIB file in the folder and see if that prevents errors during the compiling process.
If you are unable to make the corrections to get it to compile you will need to contact the author of the mib for corrections.
