I've compiled Linux PPC binaries[1] if anyone would like to test them. They're 32-bit binaries compiled on a G4 Mac mini so they ought to work on a G5 as well since I was unable to compile the 3.6 binaries on my G5 and ended up doing the same thing... This package path is /usr/local instead of /usr like the PPC binaries posted on osuosl.org.
Here's the output from the about:buildconfig page using default options from configure: Build platform target powerpc-unknown-linux-gnu Build tools Compiler Version Compiler flags gcc gcc version 4.4.5 (Debian 4.4.5-8) -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -pedantic -Wno-long-long -fno-strict-aliasing -pthread -pipe -DNDEBUG -DTRIMMED -pipe -O3 c++ gcc version 4.4.5 (Debian 4.4.5-8) -fno-rtti -fno-exceptions -Wall -Wpointer-arith -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wcast-align -Wno-invalid-offsetof -Wno-variadic-macros -Werror=return-type -pedantic -Wno-long-long -fno-strict-aliasing -fshort-wchar -pthread -pipe -DNDEBUG -DTRIMMED -pipe -O3 Configure arguments --disable-accessibility --disable-calendar --disable-chatzilla --disable-composer --disable-crashreporter --disable-debug --disable-elf-dynstr-gc --disable-installer --disable-ipc --disable-ldap --disable-mailnews --disable-mochitest --disable-negotiateauth --disable-official-branding --disable-profilesharing --disable-system-cairo --disable-tests --disable-toolkit-qt --disable-updater --disable-xinerama --disable-xprint --enable-application=browser --enable-crypto --enable-default-toolkit=cairo-gtk2 '--enable-extensions=default spellcheck' --enable-freetype2 '--enable-optimize=-pipe -O3' --enable-pango --enable-strip --enable-svg --enable-svg-renderer=cairo --enable-toolkit-cairo-gtk2 --enable-xft --prefix=/usr/local --with-branding=browser/branding/unofficial --with-distribution-id=org.gnu.gnuzilla --with-system-jpeg --with-system-zlib --with-user-appdir=.gnuzilla -Gary 1. http://dl.dropbox.com/u/20597767/ppclinux/icecat-4.0.1-linuxppcbin.tar.bz2 -- http://gnuzilla.gnu.org
