So I played around with compiling Camino. Instead of making a Universal build, I told it to just use the Intel SDK. I also put it prebinding. Here is my ~/mozilla/.mozconfig Code: . $topsrcdir/camino/config/mozconfig ac_add_options --enable-static ac_add_options --enable-prebinding ac_add_options --with-macos-sdk=/Developer/SDKs/MacOSX10.4u.sdk ac_add_options --disable-tests mk_add_options MOZ_MAKE_FLAGS=-j4 Wow is it fast! Much faster. But I'm unsure about what the differences are between 1.1 Beta and what is sitting in their CVS.
