Problems building on Tiger...

Hey everyone, I'm trying to get Firefox to build on Tiger (10.4). I got 
patch #13 from the bug page 
(https://bugzilla.mozilla.org/show_bug.cgi?id=292530); I patched it from a 
directory up (I have mozilla as a directory in my root, I patch from the 
root), and then ran the autoconf in /sw/bin in the directories /mozilla and 
/mozilla/nsprpub. My .mozconfig file looks like this:

. $topsrcdir/browser/config/mozconfig
mk_add_options MOZ_OBJDIR=/moz_out


I know the patch from the bug page is supposed to fix all the problems 
compiling in Tiger, but I still get the following error when I try to build 
with the command

sudo make -f client.mk build

I get it about 3 hours into the build before it barfs -- I'm running the 
make on a humble eMac:

/moz_out/config/nsinstall -L /moz_out/xpfe/bootstrap/appleevents -m 644 
libappleevents_s.a ../../../dist/lib
NEXT_ROOT= /Developer/Tools/sdp -fa -o mozillaSuite.r 
/mozilla/xpfe/bootstrap/appleevents/mozilla.sdef
/bin/sh: line 1: /Developer/Tools/sdp: No such file or directory
make[3]: *** [mozillaSuite.rsrc] Error 127
make[2]: *** [tier_9] Error 2
make[1]: *** [default] Error 2
make: *** [build] Error 2

I know that the patch is supposed to address the sdp issue. Any ideas what 
I'm doing wrong?
