In addition, the Mozilla project has a script (unfortunately I forget the exact name) which takes 2 single-architecture trees and combines them via lipo. It creates a new tree that contains all files that are the same in the 2 old trees. Any differing files that are binaries it combines via lipo. Any differing files that aren't binaries it tosses (can't do anything else with them), so you have to be careful in some projects (if, say, it builds a header file for distribution that changes per-architecture), but in general it works quite well.

Bob Ippolito's py2app package (which wraps up Python applications into

standard Mac .app bundles) has a separate script/command-line tool

called macho_standalone, which scans an app bundle and rewrites all the

linker bits so that the dylibs in the app bundle are self-contained. It

runs install_name_tool on them, IIRC. You may want to Google for

"macho_standalone" to find the most recent version and documentation.
