I adapted elephant to work with Allegro 7.0. It was easy to do but I
didn't test it carefully as I'm not using anything fancy from elephant
(just persistent classes, btrees and transactions).  The regression
tests show:

3 out of 85 total tests failed: ARRAYS-1, NO-EVAL-INITFORM, 
   UPDATE-CLASS.

I had to process the libpthread.so for Allegro to be able to load it
(they must be shared libraries):

$ ld -shared -o <some directory>/libpthread.so /lib/tls/libpthread.so.0

Then, on the file sleepycat.lisp, include (change) the following:

  #+linux
  (unless
      #+allegro (uffi:load-foreign-library "<some directory>/libpthread.so" :module "pthread")
      #-allegro (uffi:load-foreign-library "/lib/tls/libpthread.so.0" :module "pthread")
    (error "Couldn't load libpthread!"))

It works for me but, anyway, maybe the library is not really needed.

Best regards,
