Steel Bank Common Lisp

Hi all,

I'm trying to install SBCL on my OpenBSD box:
OpenBSD 4.1 GENERIC.MP#1152 amd64

I downloaded the 0.8.1 binary from the sbcl.org site and installed it in
the usual place (/usr/local/) using install.sh.

$ sbcl
/usr/local/bin/sbcl[1]: syntax error: `(' unexpected

Any thoughts?  I didn't see anything similar in the archives.

TIA,
dnm
