install libRmath on Mac OS X with Homebrew - r

Question

I would like to install libRmath.dylib on Mac OS X (Mavericks) preferably with Homebrew since I already use this package manager.
I did not find a formula for libRmath, but I did find a formula for R so I tried to extend it with (see entire file at end):
# Also build libRmath.dylib
system "cd src/nmath/standalone"
system "make"
system "make install"
system "cd ../../.."
lib.mkpath
ln_s prefix+"R.framework/Resources/lib/", lib
The commands ./configure; cd src/nmath/standalone; make do create libRmath.dylib if I execute them manually. But not using brew install r. I cannot find libRmath.dylib in Cellar. What am I doing wrong? (Note that I am new to Ruby and Homebrew's formula.)
Below is the entire file.
require 'formula'
class RDownloadStrategy < SubversionDownloadStrategy
def stage
quiet_safe_system 'cp', '-r', #clone, Dir.pwd
Dir.chdir cache_filename
end
end

To enable rJava support, run the following command:
R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers

Formula r now has the option with-librmath-only which only builds the standalone libRmath library.
