Like most tools from the suckless-project, dmenu lives and dies with the patches users are able to apply. To make it easy for users, I'd like to request the addition of the epatch_user-function to dmenu's ebuild; if needed, warn the user that a dmenu without Gentoo approved patches will find no support from Gentoo devs. Reproducible: Always
Thank you for reporting. I have added epatch_user in 4.5-r2.
