Starting from an up-to-date, clean, identical pkgsrc tree -- I used 
rsync to copy the tree from one machine to the other -- I tried 
building mozilla 1.7.  The build succeeded on the -current (2.0G, from 
yesterday) machine, but not on the 1.6.2 machine.  I've noted this as 
an updated to pkg/26125.
