Does rattle depend on testing's ggobi?

Hello All,

I'm trying to install rattle from source on a AMD64 machine running etch.  I 
have two packages installed from the etch backport 
(r-cran-rodbc and r-cran-rsprng) but all the rest installed from source.  I'm 
trying to install rattle, but 

install.packages("rattle", dependencies=TRUE)

Tries to install rggobi, which complains about the version of libggobi.  Does 
this mean that there isn't a way I can install rattle on etch?

* Installing *source* package 'rggobi' ...
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GGOBI... configure: error: Package requirements (ggobi >= 2.1.6) 
were not met:

Requested 'ggobi >= 2.1.6' but version of libggobi is 2.1.4
