Good. You were supposed to stop here :)

|  Version 0.82 available at http://streaming.stat.iastate.edu/CRAN

You are confusing

a) having a _pre-compiled binary_ installed (0.76) 
   ===> this implies only libraries for running this

b) having the ability to _locally compile_
   ===> this requires matching header files etc provided by the -dev
   packages.

And a) !=  b).  We provide a) because b) is harder as you discover below. 

Unless you are reasonably experienced with your Linux distro of choice it
is
somewhat difficult to build certain packages, especially when they have
hardware dependencies.  

Which is _precisely_ why we provide the binaries.

Now, a good compromise is to look at the _source of pre-built package_ as
this contains the Debian/Ubuntu-specific knowledge that the generic source
does not have. In particular:

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

leading to install 

	libgl1-mesa-dev or libgl-dev 
	libglu1-mesa-dev or libglu-dev 
	libpng12-dev 
	libx11-dev 
	libxt-dev 
	x11proto-core-dev
	
after which your local build will probably succeed.

There is nice way to semi-automate this, and we need to document it
better. It is somewhat more advanced though.

Hth, Dirk
