This uses the prebuilt mac binaries on CRAN which means they may not work correctly.

Note that it works if I use `devtools::install_github("symengine/symengine.R")`

Not sure; This is the output at the top: ``` Current runner version: '2.274.2' Operating System Mac OS X 10.15.7 19H15 Virtual Environment Environment: macos-10.15 Version: 20201130.3 Included Software: https://github.com/actions/virtual-environments/blob/macOS-10.15/20201130.3/images/macos/macos-10.15-Readme.md...

More information about the virtual machine is here: https://github.com/actions/virtual-environments/blob/main/images/macos/macos-10.15-Readme.md I believe it uses the Microsoft Azure framework if that helps.

There flags are here: ``` CC="clang -mmacosx-version-min=10.13" CXX="clang++ -mmacosx-version-min=10.13" OBJC="clang -mmacosx-version-min=10.13" FC="gfortran -mmacosx-version-min=10.13" F77="gfortran -mmacosx-version-min=10.13" CFLAGS='-Wall -g -O2' CXXFLAGS='-Wall -g -O2' OBJCFLAGS='-Wall -g -O2' FCFLAGS='-Wall -g -O2' F77FLAGS='-Wall -g -O2'...

I'm unsure since the build hasn't completed, but `install.packages("symengine", type="source")` seems to work https://github.com/nlmixrdevelopment/RxODE/runs/1538236241?check_suite_focus=true

The build does work. My guess is that it has to do with the `-mmacosx-version-min=10.13` flag.

Note that travis is going away at the end of this year, others will probably use github actions as a replacement.

I actually do use matricies, I had forgotten; Are they supported in `symengine.R`? It seems it isn't yet: ```R > S("Matrix([[a, b], [c, d]])") (FunctionSymbol) Matrix(a, b, c, d) ```
