I install the binary package for Darwin (sbcl-1.0.23-x86-darwin-binary.tar.bz2) on 10.4. Why do I get a bus error when I try to run sbcl?

~/sbcl me$ ls -a
.       ..
~/sbcl me$ cd ../Desktop/sbcl-1.0.23-x86-darwin
~/Desktop/sbcl-1.0.23-x86-darwin me$ unset SBCL_HOME 
~/Desktop/sbcl-1.0.23-x86-darwin me$ set | grep SBCL
_=SBCL_HOME
