Installation attempts

• I followed instructions at https://www.r-inla.org/download-install and ran 'install.packages("INLA",repos=c(getOption("repos"),INLA="https://inla.r-inla-download.org/R/stable"), dep=TRUE)'. I also tried the testing version
• I tried adding an argument 'type="binary' to the above call, as seen in a stack exchange thread
• At some point, I found that the path to the binary was ''/Users/ufuoma/Library/R/x86_64/4.5/library/INLA/bin/mac.arm64/inla" which seemed to be different than expected
  • I tried creating a symbolic link in Terminal using 'cd /Users/ufuoma/Library/R/x86_64/4.5/library/INLA/bin/mac

    mkdir -p 64bit

    ln -s ../mac.arm64/inla 64bit/inla'

Error

• No matter what I've attempted, whenever I run 'file.exists(system.file("bin/mac/64bit/inla", package = "INLA"))', I get FALSE
  
• Whenever I try to load INLA using library(INLA), it's successful. If I try to run a tester model, I get 'Error in inla.call.builtin() : INLA installation error; no such file '

[Helpdesk (Haavard Rue)]

do you use the R from CRAN? if you use R from brew, it will not 'work' out-of-
the box.
