    chicken-install's -keep-installed looks in prefix
    
    Instead of using "extension-information" to check whether the egg
    already exists, we use "ext-version" in the filter procedure which
    decides which eggs to remove from consideration when installing.
    
    Ext-version looks under prefix, while extension-information uses the
    system-wide egg location.
