x11-wm/dwm cannot be compiled with XFT support option. The cause is that SHA256 and SIZE records in distinfo file of the patch, dwm-6.0-xft.diff, which is applied only if you enable XFT option in configuration are wrong.
Xft support was mainlined in dwm-6.1. I'm not sure if the syntax is same as dwm-6.0-xft.diff but the patch is no longer available. And it wasn't mirrored due to XFT option being off by default. http://lists.suckless.org/dev/1511/27504.html
To clarify (I believe), the update to 6.1 in bug 204658 resolves this issue when it is committed. If so, I don't believe maintainer-feedback is required here Jan, please unset the flag if that's correct. Reporter is committer, assign accordingly
