brew switch libfoo mycopy  You can use brew switch to switch between versions of the same package  if it s installed as versioned subdirectories under Cellar  lt packagename gt    This will list versions installed   for example I had Cellar sdl2 2 0 3  I ve compiled into Cellar sdl2 2 0 4   brew info sdl2   Then to switch between them  brew switch sdl2 2 0 4 brew info    Info now shows   next to the 2 0 4  To install under Cellar  lt packagename gt   lt version gt  from source you can do for example  cd   somewhere src foo-2 0 4   configure --prefix   brew --Cellar  foo 2 0 4 make   check where it gets installed with  make install -n   if all looks correct  make install   Then from cd   brew --Cellar  do the switch between version   I m using brew version 0 9 5
