No worries Alex - completely understand.
Now that you've created a github for rsruby, I deleted mine and forked yours instead, to make things easier for you.
So some of the instructions below no longer work. Currently, to install RSRuby with R 2.8.0, do this:
$ gem sources -a http://gems.github.com (you only have to do this once)
$ sudo gem install wwood-rsruby -- --with-R-dir=/usr/lib/R/ --with-R-include=/usr/share/R/include/
If you merge my diff into your repo, Alex, then it will be
$ sudo gem install alexgutteridge-rsruby -- --with-R-dir=/usr/lib/R/ --with-R-include=/usr/share/R/include/
instead.

Hi Ben,
Thanks for this. Sorry I've not been able to chime in earlier, but the day job has completely taken over in the last few weeks *sigh*.
I'm going to try and get something on github sorted out and then tackle the list of rsruby patches which have been building up.

Actually, the gem won't work, because I haven't made a rsruby.gemspec file in the repo on github (yet). You'll have to download/git clone and then run
$ rake gem
to create the gem, and then something like
$ sudo gem install pkg/rsruby-0.5.1.gem -- --with-R-dir=/usr/lib/R/ --with-R-include=/usr/share/R/include/

I believe there is a bug in the CRAN Ubuntu and debian packages such that Rdevices.h is not included in any packages, and therefore installation won't work using the newest versions, but does using the official Ubuntu repo version 2.7.1-2 at least.

I just came across a problem installing that I've now managed to fix, and thought I might post it online since googling for it didn't help me.
Installing rsruby gave me this problem
$ sudo gem install rsruby -- --with-R-dir=/usr/lib/R/
--with-R-include=/usr/share/R/include/
Building native extensions. This could take a while...
ERROR: Error installing rsruby:

On Ubuntu Hardy, this was fixed by installing the r-base-core package, which has the Rdevices.h file. It was confusing to me that it wasn't in the r-core-dev package.
$ sudo apt-get install r-base-core
$ sudo gem install rsruby -- --with-R-dir=/usr/lib/R/ --with-R-include=/usr/share/R/include/Building native extensions. This could take a while...
