Dear list members,
I am a total newcomer to linux and would like to have some help in the installation of bioconductor packages on my newly installed ubuntu 11.10 system. I have installed R and many of the CRAN packages. I am having some difficulties in installing the EBImage package on running the command - bioClite('EBImage'). The ImageMagick installation is recognized alright, but I get the following error about the gtk package :
 installing *source* package ‘EBImage’ ...
checking for Magick-config... yes
* found ImageMagick version 6.7.3 Q16 
* found ImageMagick includes in -I/usr/local/include/ImageMagick
checking for pkg-config... yes
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
* GTK+2.0 not found: compiling without GTK+ support

Running gtk-demo on the terminal confirms that gtk is not installed. 

Now, I would like how I should install the gtk package. When I look at Synaptic, I see a whole lot of gtk programs. Which one should I choose? What surprises me is that I have RGtk2 and rattle packages installed. I get no error message on loading RGtk2. How is this possible without a gtk installation?

I would appreciate getting some instructions on installing gtk.
Thanking you,
