mako won't build? where to place the binaries?

[Akirapearl]

Hi, so I recently started configuring niri as my main wm, and while installing mako, following the README.md isntructions, I found this deadend.

Failed to acquire service name: File exists
Is a notification daemon already running?

OS: Debian 13 trixie (testing) Kernel: 6.12 DE: KDE 6.3.4 WM: KWin (Wayland)

I believe nothing is running nor was installed, since i tried that both from kde and from niri's floating session (like launched from tty running on kde). Can I do anything else to fix this? been digging around for a while but can't seem to find a solution.
