OS X build problems

hello,

I'm trying to build Mozilla on OS X 10.4 Tiger. I followed the OS X
build instuctions on the mozilla website and everything went pretty
smoothly, except that it broke during the compilation stage. These are
the last few lines from the build log:

MoreFilesX.c
gcc -o MoreFilesX.o -c -DOSTYPE=\"Darwin8.1.0\" -DOSARCH=\"Darwin\"
-I../../dist/include/macmorefiles -I../../dist/include
-I/Users/yariv/Documents/dev/mozilla/dist/include/nspr        -fPIC
-Wall -W -Wno-unused -Wpointer-arith -Wcast-align -Wno-long-long
-fpascal-strings -no-cpp-precomp -fno-common
-I/Developer/Headers/FlatCarbon -pipe  -DDEBUG -D_DEBUG -DDEBUG_yariv
-DTRACING -g   -include ../../mozilla-config.h -DMOZILLA_CLIENT
-Wp,-MD,.deps/MoreFilesX.pp MoreFilesX.c
In file included from MoreFilesX.c:80:
MoreFilesX.h:1341: error: conflicting types for 'FSLockRange'

MoreFilesX.h:1364: error: conflicting types for 'FSUnlockRange'

make[3]: *** [MoreFilesX.o] Error 1
make[2]: *** [libs] Error 2
make[1]: *** [tier_2] Error 2
make: *** [default] Error 2


It appears as though the Mozilla file MoreFilesX.h has redefines
symbols that are in Files.h in CarbonCore. I'm not sure how to proceed
at this point. Any help would be greatly appreciated.

Thanks,
Yariv
