@akkartik New build instructions in the README here:

https://git.sr.ht/~pbatch/SoundMantra

I have force-pushed an updated mnolth repo on github, which I will fix later (yay fossil git export). Use this instead of the sourcehut URL in the README (the sourcehut mnodes repo should be fine):

https://github.com/PaulBatchelor/mnolth

If you run into any issues, let me know...
