good evening;
on the occasion of pushing de.setf.graphics down the wire, when i built it for ccl/sbcl i did an obligatory pull on asdf and observe that something changed in the treatment of modules' component relative pathnames. with the effect that it was no longer possible possible to build clx. the clx-0-7-4 version as (:relative) specification in module pathnames which ran afoul of the asdf changes. i applied the same tactic as i have previously found effective for source file components and was able to build. the diff [1] is posted with the graphics sources.
on other semi-related matters, i can report, that i have now an s3 ami (linux-2.6.31+ubuntu++^3) with which i can boot an ec2 instance with all pieces in place to run the target lisp implementations.
