unble to quickload

[mooseyboots]

when i run (ql:quickload :xpath) i get the following:

Lock on package COMMON-LISP violated when
proclaiming nil as a function while in package XPATH.
   [Condition of type symbol-package-locked-error]

  Common Lisp Hyperspec, 11.1.2.1.2 [:section]

i'm pretty new to CL so not sure what's going on. is this library still functioning? it seems to be up to date in quicklisp/ultralisp.

What do you get from (ql:where-is-system "xpath")?
