I plan to use home-brew to install gcc, gsl, ffmpeg, and scipy (for python 3).  I would say I do not envision conflicts and bugs but I’d rather ask first.

Unfortunately HB installs by default in /usr/local and requires full control so you cannot have native libraries and HB in the same place at the same time. So essentially you have to pick one or the other. There are two options:

a) install HB in another place. This allows you to keep native libraries in /usr/local and parallel HB. HB is less tested that way, though, so that's why HB is shy of recommending it.

b) ignore HB's moaning. It should be ok as long as you don't install tcl/tk via HB. It may get complicated if dependencies detect tcl/tk so for safety you could rename the .pc files and the t*Config.sh files if you don't expect to compile R packages that depend on tcl/tk.

Cheers,
Simon
