gtk2.10.9 now needs cups headers on 10.3?

[Mark Duling]

So I went to install the latest gtk2 on 10.3, and I got the ui_msg thatI
had to remove cups-headers.  So I did and preceeded but it failed to build
complaining about cups or print something or other.  So I reinstalled
cups-headers and edited out the "exit 0" line if the conditional test for
cups-headers.  Then it installed fine.  So it appears that gtk2 on 10.3
fails without cups-headers, whereas before (I am told) it failed with it. 
Does that make any sense?
