I think that is a typo; try to find in lisplab.asd line with:

 :module :/shared/quadpack/

and change it to:

 :module :shared/quadpack
 
this will continue compilation. However, from what I could see from
playing with it, it will fail then at 'shared/slatec/src/dcsevl.lisp',
because initial types are single-float, but declared as double-float.

To make it working, you will need to change single-float constants
(e.g. 0.0 or 0.5) to double-float, like 0.0d0 or 0.5d0. The same issue
will arise with other files from slatec package.

Or, to have double-float as default format, preprend this line to sbcl
command:

  sbcl --eval "(setf *read-default-float-format* 'double-float)"
       # other --eval args
       
After that, it will fail again in 'quadpack' because f2cl didn't export
all functions. In file 'shared/quadpack/f2cl-package.lisp' add this:

  #:cdabs #:zsqrt #:dimag #:dcmplx #:dconjg
  
to be part of f2cl-lib package. And that should be it; hopefully :)
