Installing rstan on Posit cloud does not work

Posit people look at this posts from time to time, and you could also try to contact technical support from within Posit Cloud itself but I suspect there is a non-trivial technical reason or ven maybe a licensing issue that prevents them to make a binary available.

Even if you manage to get rstan installed in a base project you can share with your students, I doubt they will be able to do much with it considering the 1 GB RAM limit for free accounts.
