Build fails: yst-0.7.1.3 from Cabal on MacOS -- "writeDocbook5" capitalization?

I get the following error attempting to install/build yst from Cabal:

This changed in pandoc 3. I will fix yst to use pandoc 3.

Thanks for the blazingly-fast response! Making the one-character capitalization change in the source code appears to solve the problem for me locally, but if there's a bigger change/fix involved, I'm not qualified for that.

You could also use the released version and use --constrain "pandoc < 3" with cabal.
