| Ubuntu Hardy rgl install fix:
| 
| The headers gl.h and glu.h are installed with the "dev" packages 
| libgl1-mesa-dev and libglu1-mesa-dev. So the fix is to run (in at 
| terminal as root)
| 
| apt-get install libgl1-mesa-dev
| apt-get install libglu1-mesa-dev

Yes, which is why the r-cran-rgl package (available in Debian for over five
years now, and hence in Ubuntu for probably 4 1/2) has the following
Build-Depends (with my manual indentation here):

  Build-Depends: debhelper (>= 5.0.0), r-base-dev (>= 2.8.1), cdbs, \
  	      libgl1-mesa-dev | libgl-dev, libglu1-mesa-dev | libglu-dev, \
	      libpng12-dev, libx11-dev, libxt-dev, x11proto-core-dev 
 
| then
| R
| .....
| install.packages("rgl")
| 
| etc.

Let's not forget the 'sudo apt-get install r-cran-rgl' alternative.
 
| Ubuntu Hardy rJava install fix:
| 
| Needed to get Sun JDK (not JRE)
| 
| Then add new
| ln -s /usr/java/jdkxxxxx/bin/java java
| and
| ln -s /usr/java/jdkxxxxx/bin/javac javac
| 
| where xxxxxx is the version information on the jdk directory name -- in 
| my case 1.6.0_13 (see below)
| 
| Then
| 
| R CMD javareconf
| 
| still fails to find the java compiler.
| 
| Seems $JAVA_HOME may not be defined.
| 
| Try
| export JAVA_HOME="/usr/java/jdk1.6.0_13/"
| 
| Then (as root)
| 
| R CMD javareconf
| 
| seems to work.
| Then rJava installed OK. I was then able to install RWeka (my original 
| objective) and it seems to run OK.

Likewise, the r-cran-rjava package has 

   Build-Depends: debhelper (>= 7.0.0), r-base-dev (>= 2.8.1), cdbs, \
   		  openjdk-6-jdk, automake

and R is now configured for this Java version at the built.


Again, questions on the r-sig-debian list may have been of help.

Hope this helps,  Dirk
