$ yum provides protobuf

...

protobuf-2.2.0-2.fc11.i586 : Protocol Buffers - Google's data 
interchange format
Repo        : installed
Matched from:
Other       : Provides-match: protobuf

Line 378 is the middle line of :

     int GetSize() const;
     void Free();
     int SpaceUsedExcludingSelf() const;

I'll keep looking
