[elephant-devel] Problems installing elephant on gentoo linux/CMUCL

[Andrew Blumberg]

hi garry,

 	so direct-slot-definition-class should (according to the spec) 
have the signature ((foo class) &rest initargs), and our specialization of 
that method in the elephant sources conforms to this.  your backtrace 
below indicates that your cmucl seems to disagree. . .

 	in addition to indicating the version information about cmucl, it 
would be extremely helpful if you could find out what argument pattern 
that pcl:direct-slot-definition-class thinks it wants in your setup.

 	i'd be sort of surprised if the new patches borked this somehow; 
i'm guessing maybe you have an older pcl implementation.
