	More important than the specific model of Intel cpu (E6750) would
	be the version of mjpegtools being used.

	That sounds like an older version of mjpegtools.  Use the CVS version.
	The CVS version knows about 'nocona' - that's what is in the Core2 Duo
	MacBookPro.

	Did you see and try the "--with-extra-cflags" option?  That can be
	used to override options.  

	Recent version (cvs) of mjpegtools should detect the nocona processor
	type but if that doesn't happen then try:

	    --with-extra-cflags="-march=nocona -mtune=nocona"
