Ha! I hadn't seen this and submitted #60444 Does the json-rpc package need autoconf automake and TeX? I got it to work with guile-3, guile-json-3 as inputs and pkg-config as a native input. (Actually now that I think about it I guess guile-json isn't needed) Also why would guile be a native input for json-rpc? Should just be an input right? Thanks, Abhishek.
