Rfast package install error

[AHuffmyer]

I was trying to install a package that required Rfast package as a dependency. I got an error that looked like this:

── R CMD build ────────────────────────────────────────────────────────────

I got around this by forcing an install of an older version with:

remotes::install_version("Rfast", version = "2.0.8")

I was then able to install.
