Non myth related ebuilds should not cause you any harm.


I would look at the ebuild trees at

https://github.com/MythTV/packaging/tree/master/Gentoo

and

https://github.com/MarcT/mt-mythtv/tree/0.24-fixes

to see what is needed (eclass ...) in your own copy of these ebuilds.


The first link (official ebuilds) does not have the patch for the dvb
change in mythtv however there is a pull request to fix that. The
second link (a project I am involved in) has the update since I
updated the ebuilds this weekend.
