When I "emerged" kdevelop 3.3.3, with this USE flags: emerge -pv kdevelop [ebuild R ] dev-util/kdevelop-3.3.3 USE="cvs java php sql -ada -arts -clearcase -debug -fortran -haskell -pascal -perforce -perl -python -ruby -subversion -xinerama" I looked at the end of configure script and it said: You're missing the dot program. It is still possible to run and use KDevelop without it, but you will not be able to use the new graphical classbrowser. In order to get a dot copy, go to www.graphviz.org and download the graphviz package. I did a emerge graphviz manually and after rerun emerge of kdevelop. And the message above dissapeared (I asume this functions will be compiled). Wouldn't be far better to include an graphviz use in USE list of kdevelop? Thanks.
Added graphviz support. Thanks for the report.
