Are you sure that there is a file Segment.bmx (which seems to be imported by SegmentInfo.bmx)?
If so, did you try to disable quickbuild just in case you did, by error, compile segment.bmx once on its own?( because if a bmx is compiled on its own, the generated object files won't work for import into anything else, thus quick build must be disabled to rebuild them for linking)
