the workaround is to emerge with -gtkstyle

Please give me a full build.log

[Comment 3 Markos Chandras (RETIRED) 2009-02-15 21:14:30 UTC]

And could you please emerge x11-libs/gtk+:2 and see if that fixes this issue?

Thanks

Ok this is fixed on CVS. gtk+:2 is needed if you want to install qt-gui-4.5.0_rc1 with gtkstyle use flag

Thanks for reporting

For the log:  Qt's configure runs the command

  # pkg-config --cflags gtk+-2.0 ">=" 2.10 atk

internally.  There's multiple reasons why this could fail, for example:

  # pkg-config --cflags gtk+-2.0 ">=" 2.10 atk
  Package libpng12 was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libpng12.pc'
  to the PKG_CONFIG_PATH environment variable
  Package 'libpng12', required by 'cairo', not found

Here the fix seems re-emerging cairo.  So if you get

  "Gtk theme support cannot be enabled due to functionality tests!"

from emerging qt-gui (not just 4.5.0_rc1-r1) a look at the output of said pkg-config call could help.
