As far as I can tell the entries in '/var/lib/dpkg/available' are added as you install packages and the entries remain there even if you uninstall the package.
Did you actually look in '/var/lib/dpkg/available' with e text editor or with, for example, 'cat /var/lib/dpkg/available | grep -A 11 "Package: libxen3"'? Or did you run something like 'aptitude show libxen3'? If I run 'cat /var/lib/dpkg/available | grep -A 11 "Package: libxen3"' I get no output since I never installed the package. But when I run 'aptitude show libxen3' because 'aptitude' doesn't look in '/var/lib/dpkg/available', but get's the info from somewhere else (the repository I assume).
