If I'm in SLIME and I enter (ql:quickload :cl-ppcre) in the REPL I get this error:

READ from #<INPUT STRING-INPUT-STREAM>: there is no package with name #1="QL"

[Condition of type SYSTEM::SIMPLE-PACKAGE-ERROR]

However, if I enter the same in the CCL command line (no SLIME) I get this:

[mrice@sabal ~]$ ccl

Welcome to Clozure Common Lisp Version 1.9-r15757 (LinuxX8664)!

? (ql:quickload :cl-ppcre)

To load "cl-ppcre":

Load 1 ASDF system:

cl-ppcre

; Loading "cl-ppcre"

(:CL-PPCRE)

Why the difference?

I ran a regular expression example from the CCL command line and PPCRE seems to be working OK.

What must I do to use Quicklisp from the SLIME REPL?
