 	it will redo the link step. The remedy is to use SGI's much
! 	smarter "smake " utility (/usr/sbin/smake), or GNU make. If
 	you set the first line of the Makefile to #!/usr/sbin/smake
 	smake will be invoked by make (likewise for GNU make).

! 	There is a bug in the SGI compiler's optimization that causes a
! 	bus error in PyComplex_ImagAsDouble(); this has been reported to
! 	be triggered when importing Numeric Python and may be caused at
! 	other times. The work-around is to build Python, delete the
! 	Objects/complexobject.o file, and then recompile without
! 	optimization (use "make OPT=").
