[Chicken-users] MacOSX setup-helper install error

[.alyn.post.]

I'm running Mac OS X 10.8.2 and have just installed the latest
XCode+XCode command-line tools.  I've built chicken 4.8.0, and
am trying to install the setup-helper egg.  I get the following
error.  I'm not familiar with install_name_tool, though I gather
it's a piece of XCode and/or some Mac OS X-specific piece of the
toolchain.

Are any of you familiar enough with this platform to shed some
light on what is going on?
