qt4-mac build error

[Troy Telford]

I'm getting the following error when I try to upgrade qt4-mac:

I've tried building it a number of times, cleaned it, etc.  No real
difference - it fails.  And I really need it to work as a few things
that I'm using need qt4-mac to be upgraded.  (The currently installed
build isn't working for a number of things, actually)
