Hi Hans, 

With dev-lisp/cmucl-19d_pre1, dev-lisp/sbcl-0.9.18 and
dev-lisp/clisp-2.41 (all committed to CVS last night), we've stopped
using the Common Lisp Controller.  Before with CMUCL 19c and the
Common Lisp Controller, the clx subsystem, and other CMUCL subsystems
(clm, gray-streams, simple-streams, hemlock etc.) were installed with
ASDF system definitions.

Now you need to do things the CMUCL way, the way the upstream
developers intended:

$ lisp
CMU Common Lisp CVS Head 2006-10-28 01:59:57 (19D), running on localhost

; [GC will next occur when at least 14,940,480 bytes are in use.]
("CLX")

We have an upgrade guide here:

    http://www.gentoo.org/proj/en/common-lisp/guide.xml

It describes how to use the Common Lisp libraries in the absence of
the Common Lisp Controller.  It doesn't mention the change to loading
CLX for CMUCL though.  I'll add a section on that tonight and also
link the guide from the project page:

I'm not sure what would cause that problem, especially since your
CMUCL 19c ran fine under the same configuration.  Could you file a bug
report?  Make sure to include the output of emerge --info.

Best regards,

Matt
