I add the USE flag "doc" , when I emerge -uvND world, portage told me to add the "jadetex" and "tk" into my USE, and I did. then, the circular dependence occured. Reproducible: Always Steps to Reproduce: 1 add "doc jadetex tk" in USE of the /etc/make.conf. 2 emerge -uvND world. 3. Actual Results: emerge -uvND world These are the packages that would be merged, in order: Calculating dependencies... done!
