I never thought of keeping a copy of rc in /bin. What I came up with was

path at the time it was run. That sounds complicated...
Basically, run it in a dir with rc and/or awk scripts and the rc and awk
you want to use in dirs at the head of path. It will fix the #! lines. It
searches recursively too. I've used it to fix plan9port itself after a
move, which p9p's own INSTALL won't do.
My main motive was that I wanted most of my scripts to run on
Plan 9 as well as my BSD/Linux systems without any hassle. At
any rate, I'd rather have a shebang line that works everywhere
than a script that modifies them all, especially since my
scripts tend to either live on a network filesystem or move
around a lot via rsync or hg.
