Trouble installing rstanarm on Linux

I’m having trouble installing rstanarm on my Ubuntu 20.04.3 system. I’ve tried both the CRAN version (2.21.1) via install.packages('rstanarm') as well as the dev version via remotes::install_github('stan-dev/rstanarm') (and also remotes::install_github('stan-dev/rstanarm',INSTALL_opts="--no-multiarch",force=T)). I have gcc 9.3.0 installed, and my ~/.R/Makefile is empty. Any suggestions?

Here’s the final bit of output from the CRAN-version attempt:

Error: package or namespace load failed for ‘rstanarm’ in dyn.load(file, DLLpath = DLLpath, ...):

Can you monitor RAM usage while building? Rstanarm uses a lot of RAM when building from source.
