Note the (cached) here. A misfeature of ./configure is that it
saves the result of previous configuration runs, so once things
go wrong once, they will never go right until you remove 
the file 'config.cache'. 

(IMO, caching should not be done except when specifically enabled -
since it only helps people who frequently reconfigure.)

The relevant thing is not this problem, but what happened during
GTK's configure so that it didn't find your X libraries.

(I really need to change configure so that it aborts under these
 circumstances).

The place to look for error messages is the file 'config.log' which is
generated when you run configure. (Not the output of the ./configure
program which is just a summary)
