Please help!

I can not install minfi but not load it.  It says it can't find rgl.so

I have tried updating all packages from source: biocLite(pkgs, type="source") and I get a load of warnings including 

14: In install.packages(pkgs = doing, lib = lib, ...) :
  installation of package ‘minfi’ had non-zero exit status

I'm running R version 3.2.3 under El Capitan but I note the installation URL has mavericks in the address.  Is this the problem?
