Let me comment about why we don't do this.  For a large percentage of open source packages (the figure 80% is bandied about) one could simply run "make" twice with appropriate options and then lipo all the libs and binaries together.  This could obviously be automated by Fink.

However, we would have to work hard for the additional 10% or 20% -- lots of special cases there.  And this is pretty much an all-or-nothing proposition:  either Fink is built with fat binaries and then every Fink compile can correctly assume that all libs it accesses are fat, or not -- otherwise, we would need a mechanism to specify which packages were fat and which weren't, and the dependency checking on that would be horrendous.

Had Fink begun after OS X on i386 had been introduced, the story might be different... Of course these days, one can argue in favor of including 4 architectures (i386/x86_64/ppc/ppc64) which might even grow in the future, if open source compiling on Apple's chips for mobile devices ever gets going...
