This is caused because in older ASDF, a version of 1.<whatever> was not considered to satisfy a version requirement of 0.<whatever>. This was changed because ASDF updated to 3.0 but was not considered satisfying 2.<whatever> as required by Quicklisp.
http://thread.gmane.org/gmane.lisp.asdf.devel/3062/focus=3066 has some info about when and why this was changed.
