for a research project I needed to install RApache on my Mac OS X 10.6.4 (Snow Leopard) machine.
It did take some time, a lot of beeping in the video documentary, a lot of recompiles…
Here is the way to do it:
1. Install Gnu Fortran on your Mac
You need to install Gnu Fortran on your Mac, because you have to build R on your Mac to run RApache.
Fortunately, there is a nicely Mac-style installer available at
Go ahead and install it.
2. Install libapreq on your Mac
libapreq2 is a library for your Apache 2 installation. Download libapreq2-2.12 (or newer) here and install it via Terminal:
tar xzvf libapreq2-2.12.tar.gz cd libapreq2-2.12 ./configure make sudo make install
3. Build R
Go to your favorite CRAN-mirror (Georg-August Universität Göttingen) and download the source for R, e.g. R-2.11.1.tar.gz (section source code for all platforms). Now build R. Watch out for the configure option –enable-R-shlib!
tar xzvf R-2.11.1.tar.gz cd R-2.11.1 ./configure --enable-R-shlib make sudo make install
4. Install RApache
Download RApache from http://biostat.mc.vanderbilt.edu/rapache/downloads.html
Install RApache with the special configure option with-apache2-apxs!
tar xzvf rapache-1.1.9.tar.gz cd rapache-1.1.9 ./configure --with-apache2-apxs=/usr/sbin/apxs sudo make sudo make install
5. Reconfigure your Apache
Go to your Apache configuration file:
cd /private/etc/apache2/ sudo pico httpd.conf
(if you have TextMate installed, just use sudo mate httpd.conf)
now add the line after the other LoadModule entries in the httpd.conf file
LoadModule R_module libexec/apache2/mod_R.so
Add the following line for debugging just below
as well as (put this somewhere at the end of the conf-file:
# Prints out a nice report about R running within Apache
Restart Apache (open up Systempreferences, select Sharing and uncheck and check Websharing).
Now you should be able to go to
(you find the name of your computer in System preferences -> Sharing if you click on websharing: if websharing is running, it shows you a link to your computer – use the second link)
to get a nice info about RApache running on your system.
After that you have to reinstall R from CRAN again, because your regular R install will be broken. Hmmmm, I hope this gives all you RApache-Macheads enough headstart to come up with a cleaner solution.
