Indeed, it seems that out of the strong recursive reverse dependencies
of the 'psych' package, 27 need compilation:

tools::package_dependencies(
 'psych', reverse=TRUE, which = 'strong', recursive=TRUE
) -> revd
tools::CRAN_package_db() -> db
db |> subset(Package %in% revd$psych) |> with(
 Package[NeedsCompilation == 'yes']
) |> length()
# [1] 27

In order to run R CMD check for them, you'll need a working compiler.
Have you got Xcode installed? Is it possible for you to install Xcode
14.3? If you don't get a better answer here and there's no answer at
<https://mac.r-project.org/>, try asking at R-SIG-Mac at r-project.org.

Hmmm, in general you shouldn't need to build the binaries when you can just
download them from CRAN. So I'd start by figuring out why that's not
happening? Is your version of R out of date? Or has one of your reverse
dependencies just been submitted to CRAN and thus doesn't have a binary yet?
