[R] RGtk2 compilation problem

[Shige Song]

Dear All,

I am trying to compile&install the package "RGtk2" on my Ubuntu 10.04
box. I did not have problem with earlier versions, but with the new
version, I got the following error message :

I noticed the requirement for the package
(http://cran.r-project.org/web/packages/RGtk2/index.html) saying
"...GTK+ (>= 2.8.0)..." The latest GTK+ is 2.20, could this be the
problem?

Many thanks.

Best,
