I know but Darwin before 6.0 (Mac OS X 10.2) used zsh as /bin/sh,
so it might be a problem on that platform.
This is the only platform that I know of that uses zsh as /bin/sh.
There might be a warning in the install part of the web page detailing 
this.

PS I used to build gcc on Mac OS X 10.1.5 (Darwin 5.5) before I got Mac 
OS X 10.2 (Darwin 6.0).
