FYI, it's easy to make this happen; simply deactivate perl5.8 and then try extracting ikiwiki. Dependencies are not guaranteed to have been installed/activated by pre-extract time. They are guaranteed to have been installed/activated by pre-configure time, however, so you may wish to postpone this check until that time.
