Current git :

    $ perl -c IkiWiki/Plugin/aggregate.pm  
    syntax error at IkiWiki/Plugin/aggregate.pm line 427, near "24;"
    IkiWiki/Plugin/aggregate.pm had compilation errors.

This prevents a Debian package build (due to t/syntax.t).

Not knowing the units being used, I don't know where to add the missing parenthesis.
