qlot is a project-local library installer.
System qlot builds fine, but the other systems signal an error in SBCL 1.2.1.
http://report.quicklisp.org/qlot/2014-07-29/failtail.txt has a build log.
Fix warnings & errors in compile-time.
Sorry and thank you for the log.
I think I could fixed them. Could you try it again?
