10.5 OS X ppc64 problem

I'm trying to install the ppc64 bit version on my server, It completes, but when I try to build PHP with postgre support, it complains about a set of libraries in the postgresql install and it dumps this:

ibs/libphp5.bundle libs/libphp5.so
ld: warning in /usr/local/pgsql/lib/libpq.dylib, file is not of required architecture
Undefined symbols for architecture ppc64:
"_PQgetResult", referenced from:
__close_pgsql_link in pgsql.o
__close_pgsql_plink in pgsql.o
SNIP--------------------------------SNIP

ld: symbol(s) not found for architecture ppc64
collect2: ld returned 1 exit status
lipo: can't open input file: /var/tmp//cc4QkRzU.out (No such file or directory)
make: *** [libs/libphp5.bundle] Error 1

I am configuring with these settings.
CFLAGS="-arch ppc -arch ppc64 -g -Os -pipe -no-cpp-precomp" CCFLAGS="-arch ppc -arch ppc64 -g -Os -pipe" CXXFLAGS="-arch ppc -arch ppc64 -g -Os -pipe" LDFLAGS="-arch ppc -arch ppc64 -bind_at_load"

All I see are issues with the ppc64 build, and the binaries are all crap. One universal binary had ppc, i386, x86_64, but no ppc64. Since everything in 10.5 is 64 bit, php will not compile with 32 bit postgre libraries (unless I missed something).

sh-3.2# file libpq.dylib
libpq.dylib: Mach-O dynamically linked shared library ppc

Can anyone offer any advice?
