That's what I'm doing in the Arch Linux ptxdist package [1]. Arch Linux
has /usr/bin/python pointing to /usr/bin/python3 instead of python2.
There's a configure flag for ptxdist and Python, but that doesn't work.

I sent a patch [2], but even that patch doesn't fix everything (there's
still some ipkg problem). Because I was too lazy I changed it that way
(modifying PATH).

I'm doing 

----- 8< --------
export PATH=$(dirname $(readlink -f "$0")):$PATH
----- >8 --------

which inclues /usr/lib/ptxdist-2011.xx.y/bin into $PATH and that works.
It's not really nice, but I think it's better than patching lots of
tools. And having scripts as executable programs is IMO still better
than having to call the interpreter manually (which is necessary with
your $PTXDIST_SED approach.

Bernhard
