If 'make' cannot detect the host, usually it means the host doesn't really matter.
To check,
type
pico configure.in
(yeah, pico is a nifty console text editor),
and check if the host names are mentioned anywhere.
If host is important, put some with BSD in it, if that one doesn't exist, try something with LINUX in it.
Otherwise, put
--host=ppc-apple-macosx
Also, if your make fails with some of these, type
make clean
before running make again.
Hope this helped..
