[cl-opengl-devel] cl-opengl not running with CLisp

I'm using the latest cl-opengl, cffi, babel, alexandria and trivial-features, and I get the following errors when I try to run glut examples: [3]> (cl-glut-examples:gears) *** - FFI::WRITE-MEMORY-AS: 5.0s0 cannot be converted to the foreign type SINGLE-FLOAT [3]> (cl-glut-examples:rb-robot) *** - FFI::FOREIGN-CALL-OUT: 0.0s0 cannot be converted to the foreign type SINGLE-FLOAT I've tried several versions of CLisp, it happens on all of them.
