title: Scales pkg do not install in my 2009 32 bit Mac mini (El Capitan) Rstudio
body: <p>I recently upgrade my 2009 Mac mini adding 2gb of ram and installing "El Capitan". For some reason when I try to install "ggplot2" the package Scales ask me for compile it, when I hit yes to continue the process a message appears saying that is unable to compile the dependency. When I check my installed packages the installed Scales version installed is the 0.4.0 and don't allow me to update it to the 0.4.1 version. I try selecting another mirror and installing manually the newer version but it dosen't work. I also install gfortran 4.2.3 and tcltk 8.5.5x11 trying to solve the compiling problem.</p>
  
  <p>The messages that appears are the following:
  -"ERROR: compilation failed for package ‘scales’"
  -"ERROR: lazy loading failed for package ‘ggplot2’"</p>
  
  <p>I will appreciate any help.</p>
  
  <p>Thanks!</p>
