Solveddata.table Error when installing from source on macOS

I've followed all the instructions on https://github.com/Rdatatable/data.table/wiki/Installation and searched StackOverflow, but I cannot get data.table to install from source (for OpenMP support) on Mac 10.14.6 with R4.0. I keep getting this error when I try to install from source:

> install.packages("data.table", type="source", Ncpus = 7)

Never mind. I figured it out and am able to install with multithreaded support. I had to change my .R/Makevars file. Here are the new contents:
