I'm not going to file a bug report, that's more time than I'm willing to spend on a project I'm not involved in. I will say I'm using Termux 0.118 and Racket 8.13 on kernel 5.10 and Android 14 and am willing to answer questions.
I just installed the package called `racket` from Termux's upstream, and it seems that they're using racket-minimal for that. Bit of a gotcha, but at least it doesn't seem like there's a bug. Thanks for the tip.
In that case, I make it quick - and refrain from any followup questions.
Did you by chance pick the "Minimal Racket" distribution?
If so, your command essentially compiled large parts of Racket and generated the entire set of documentation.
The distribution "Full Racket" is the recommended distribution for most purposes. It comes with everything pre-compiled.
