But that is not what the message indicates.  It says that it was
compiled against a newer version of the library (20007) but actually
using an older version (20006).  So something is wrong with the linker
configuration.

Also suppose that 20007 contains a bug fix that was not in 20006 and
that jed included a work-around if compiled against older versions of
the library:

   /* Some jed code */
   #if SLANG_VERSION < 20007
     /* work around a bug to avoid a SEGV */
        .
	.
   #else
     /* no need to work around the bug */
   #endif

As you can see, when compiled against 20007, the "bug-fixing" code
will not get included.  However, since the user is actually using
20006, the bug is present but the code to work-around it is not.

I hope this explains why I feel that the code should be left there.
Thanks,
