gtk+-2 dependencies

[Richard B. Pyne]

  I am finding many places where modules have dependencies that are not 
included in depends.

For example, gtk+-2 will not build without libX11, but there is no 
dependency included in the module.

Then even after installing libX11, gtk+-2 still says it isn't there:

checking for IceConnectionNumber in -lICE... no
checking for XOpenDisplay... no
configure: error: *** libX11 not found. Check 'config.log' for more details.
