I am using SBCL 1.0.32. When I try to load a package 'FOO I get the following error. If I remove the fasl files then it all compiles and load all right. I have to remove the fasl files every time I quit and try to load. What could be the reason for this ?

The name "FOO" does not designate any package. [Condition of type SB-KERNEL:SIMPLE-PACKAGE-ERROR]
