Twenty feels a bit small -- I would be a bit more generous with the 
history.
FreeBSD's tinderbox setup (http://wiki.freebsd.org/Tinderbox) has a very 
nice script/parser that summarizes where in the build the error occurred 
and gives a reasonable amount of context.  It appears to be a perl script 
(two links away from the one above), but I haven't looked at it much and 
don't know how closely it is tied to our 'buildworld' structure.  Anyway, 
it might provide some inspiration.
