Building SDL under MacOS X

i am sorry for disturbing you with my problems with this (it is not
really SDL problem but it showed to me while i was compiling SDL)
i downloaded latest src codes of SDL and then i tried to
but somewhere while calling cc it tries to include Carbon.h and in
Carbon.h is included some files ie. URLAccess/URLAccess.h i found this
file in /Developer/Headers/FlatCarbon but i didn’t find it in directory
URLAccess. Did i install something wrong? Or what should i do?
Thanks for any help.
