Here you'll find the module binaries for Apache HTTPD.
All modules have been build on Mac OS X ppc64 (Dual G5) - 10.5.0 (Leopard). Tools that I used were gcc 4.0.1 (Xcode 3.0 - powerpc-apple-darwin9-gcc-4.0.1), MacPorts 1.5.2 (libtool 1.5.24, gnu make 3.81, autoconf 2.61, automake 1.10).
Compiled with
export CFLAGS="-arch ppc" ./configure --with-apxs=/usr/sbin/apxs make sudo make install
