The fact that the original poster had obviously not used MacPorts (and perhaps did not even know what it was) suggests that the appropriate reply should be to discourage him from using it and offer a strategy with greater likelihood of success in combination with the more typical installation method for the Mac R fork. > > So: each of the approaches has it’s own pros and cons - it is only that > homebrew and Macports are not officially supported by the R team. One of the cons is that both homebrew and MacPorts requires a greater knowledge of the Unix under-pinnings of MacOS. If a poster is asking how to install MacPorts, it suggests that he don't already have such skills and perhaps doesn't even have the motivation to acquire them. (Your earlier response suggested that posting in R-SIG-Mac was the wrong way to do acquire such skills and I agree. Appears the poster has not yet developed the habit of reading supporting online documentation. He certainly did not do so regarding R-SIG-Mac. My opinion: A person who chooses not to read or heed online documentation should be actively discouraged from using either MacPorts of homebrew.)
