The attached patch provides support for 0.9.1.25 (coming soon to an anoncvs near you), which includes the newfangled WITH-COMPILATION-UNIT :SOURCE-PLIST stuff -- and breaks unpatched Slime. The patch should work with all versions between 0.9.1 and 0.9.1.25 as well. I also took the liberty of documenting Slime as supporting only the latest official release of SBCL, as opposed to a specific version....
