krunners error:

There are possibly others involved. The culprit might be the line 

check_library_exists(GL glXChooseVisual "" HAVE_GLXCHOOSEVISUAL) 

in work/systemsettings-4.0.0/kcontrol/screensaver/CMakeLists.txt (in the case of systemsettings), which is executed even if systemsettings are built with USE="-opengl".

Not sure, but I think the comment # FIXME: is have_openglxvisual found without screensaver is about this.

Possible solution would be to manually comment out this line...

P.S.: there is a little typo in systemsettings-4.0.0.ebuild. it should be $(cmake-utils_use_with ieee1394 RAW1394) instead of $(cmake-utils_usr_with ieee1394 RAW1394)

Reproducible: Always

Steps to Reproduce:
1.USE="-opengl" emerge qt
2.emerge krunner systemsettings
3.

Actual Results:  
build fails

Correct.

Yes. Should all be fixed in cvs now. Thanks for the report.
