I ran into this too and I wonder what is going on in this one. What package bundles what and where is the problem.

Comment 7 Joost Ruis 2020-09-02 22:10:07 UTC

To quickly answer this, doesn't happen with dev-util/trace-cmd-2.8.3::gentoo

Both trace-cmd and perf are part of the Linux kernel tree, so it seems that the colliding files is shared code between them from the kernel repository. Not sure what is the best way to fix this. One way may be to add libraries for each of them under a subdirectory, and another way would be to make one package depend on the other and not install the plugins in one of them.

To avoid potential problems with compatibility between the plugins, I just changed perf's plugin directory to <libdir>/perf/plugins.
