But unless your disk is almost completely full building a "thin" binary instead of a universal one isn't worth the trouble :-). Even buildtime shouldn't be noticable faster on intel macs as gcc will run the PPC and x86 builds in parallel.

I'm not sure why numpy doesn't distribute a universal binary egg, that's rather user unfriendly if you ask me. Universal binaries are the best way to package software, users shouldn't have to worry about what CPU type they have in their machine.
