This is a known issue.  Matlisp defines a function REAL in the MATLISP
package.  This collides with the symbol REAL in COMMON-LISP.  If you
continue, you will lose the symbol REAL from the CL-USER package.

    Tamas> OTOH, in-package works fine:

This is the preferred way to access Matlisp.

    Tamas> but only after I run (load "start.lisp").

The package won't exist until you load start.lisp.

    Tamas> Questions:
    Tamas> 1. do I need to load start.lisp every time I want to use matlisp?
    Tamas> 2. how can I make use-package work?

1. You can save a core file with Matlisp and everything loaded.  
2. Not sure, but you need to be careful because Matlisp defines it's
   own REAL function.
