I had *just* read your wx-dev post and was going to ask about the 

When I try this:

CFLAGS=' -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386'
LDFLAGS=' -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386'

I get this:
    checking for C compiler default output filename... configure: error: 
C compiler cannot create executables

and if remove the -sysroot part from LDFLAGS, configure runs but then I 
get quite a few errors during the final parts of make:
   /usr/bin/ld: warning Parser/acceler.o cputype (7, architecture i386) 
does not match cputype (18) for specified -arch flag: ppc (file not loaded)

I appreciate any schooling you can offer me :)
