I can see the original poster's confusion.
He has an MC68F375.
Currently available products here in this range consist of:
MC68000, MC68302, MC68331, MC68332, MC68340, MC68360, MC68F375.
The ones supported by CodeWarrior on that link consists of:
MC68302, MC68306, MC68331, MC68332, MC68340, MC68360.

It may be there's a mistake on the CodeWarrior page, and it does support the MC68F375 "out of the box". If it doesn't then there may need to be "some assembly required" in order to define an appropriate set of header files to suit the peripherals on that specific CPU model.
DJJ, do you have the debug pod hardware there for this chip? If not, then getting one might be the next challenge.
