Dear Liam,

With the latest svn checkout (36) sbcl 1.0.15 raises the following error:

There is no class named GSLL::MATRIX-DOUBLE-FLOAT.
    [Condition of type SIMPLE-ERROR]

Restarts:
  0: [RETRY] Retry performing #<ASDF:LOAD-OP NIL {1003992C31}> on 
#<ASDF:CL-SOURCE-FILE "lu" {1003CB1B01}>.
  1: [ACCEPT] Continue, treating #<ASDF:LOAD-OP NIL {1003992C31}> on 
#<ASDF:CL-SOURCE-FILE "lu" {1003CB1B01}> as having been successful.
  2: [RETRY] Retry installation
  3: [ABORT] Return to SLIME's top level.
  4: [TERMINATE-THREAD] Terminate this thread (#<THREAD "repl-thread" 
{1003BC5301}>)

when compiling the lu code.
