Spec generation fails on OpenBSD

[rpx99]

I am trying to regenerate the spec files.

After updating the path (see 171)

diff --git a/src/autowrap.lisp b/src/autowrap.lisp

and executing this command

sbcl --load "sdl2.asd" --eval "(ql:quickload '(:sdl2))" --eval "(uiop:quit)"

I get this error:

tron$ sbcl --load "sdl2.asd" --eval "(ql:quickload '(:sdl2))" --eval "(uiop:quit)"  
This is SBCL 2.4.8.openbsd.sbcl-2.4.8, an implementation of ANSI Common Lisp.

I have cloned latest cffi and cl-autowrap in my common-lisp folder (used by quicklisp).

Why is that? Thanks.

I do not have a BSD machine to investigate.
