gtk+-1.2.10 Build error - can't find X libs/inc on Snow Leopard

[mike@…]

I'm guessing there's something I've done wrong, but while trying to build gtk1 I'm getting the following error message on my newly upgraded Snow Leopard system.

I did wipe out my /opt/local dir and reinstall MacPorts 1.8 from scratch after upgrading to Snow Leopard:

checking for X... no
configure: error: 
*** X libraries or include files not found. Check 'config.log' for 
*** more details.

Config log from attempt to build gtk1.

Did you install X11 from the Snow leopard install disk?

[mike@…]

I thought I did, and X is working and the /usr/X11/include and /usr/X11/lib files are all in place, but maybe that's all from the previous version.

[jmroot (Joshua Root)]

We're not using Apple's X11 client libs any more. This probably needs either a build dependency on pkgconfig, or --x-includes/--x-libraries configure args.

I had this build failure earlier today, and resolved it by simply running 'port install xorg-libXt' and then reinstalling the port which required gtk1. (I may have had to 'port clean gtk1', I cannot recall.)

I'm not sure if simply adding xorg-libXt to the gtk1 dependencies is the right fix or not, I didn't look closely. Too many broken ports and too much work to do at the moment. :-)

Toby added xorg-libXt as a dependency in r57171 and builds fine here.
