Possible error in the source command
I recently used the source('https://openmx.ssri.psu.edu/software/getOpenMx.R') command to install OpenMx on a lab computer. It was met with the following error message:
trying URL 'https://openmx.ssri.psu.edu/software/bin/macosx/el-capitan/contrib/3.6/OpenMx_2.13.2.tgz'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL 'https://openmx.ssri.psu.edu/software/bin/macosx/el-capitan/contrib/3.6/OpenMx_2.13.2.tgz'
This occurred on a MacBook Pro running Mojave 10.14.5.
I am happy to build from GitHub instead, but I keep running into odd problems when attempting to switch clang to gcc and gfortran. Despite switching everywhere that I can find, I continue to receive an error that the code cannot compile become of a clang error.
Thought I should share the experience.
