libzmq-5 not found on Apple M1 silicon

It seems that iracket is searching for zeromq-5, but the current tagged release is for Apple M1 (and possibly everything else) is 4.3.4. In any event, the kernel won't start after I did

raco pkg install iracket
raco iracket install
jupyter lab build

These commands appear to succeed, though I did get a warning about libzmg-5.dylib on the initial raco pkg iracket install command. I could not copy the text nor reproduce the error after installing iracket again via the sequence:

raco pkg remove iracket
raco pkg install iracket

jupyter lab fails as follows once I pick the iracket kernel and attempt to evaluate a cell containing #lang iracket/lang:
