Referring to bug #935279, I see the same problem with mate-utils. There may be other packages that need fixes to dependencies. checking for mate-desktop-2.0 >= 1.27.1... no configure: error: Package requirements (mate-desktop-2.0 >= 1.27.1) were not met: Package dependency requirement 'mate-desktop-2.0 >= 1.27.1' could not be satisfied. Package 'mate-desktop-2.0' has version '1.26.2', required version is '>= 1.27.1' Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables MATE_DESKTOP_CFLAGS and MATE_DESKTOP_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. !!!

My system has the following Mate packages installed: Reproducible: Always Steps to Reproduce: 1. emerge -uUD @world # On system with Mate 1.26 installed. 2. 3. Expected Results: ebuilds for the mate-* packages should not be built until the pre-requisite packages are built.
