R devel - Aug 2005 - Different gcc versions

I have both gcc-3.4 and gcc-4.0(.1) installed on my system 
(debian-amd64 unstable), with links /usr/bin/gcc, g77, etc. to
the 3.4 versions. When I build R, the 3.4 version is picked up, 
which is fine.

However, when I 'install.packages("xyz")', R uses gcc-4.0 and
gfortran-4.0! Should I accept this or do something about it?
And if so, what? Of course, removing all 4.0 versions would 
help, but what if I don't want to do that?

There are several way about it. 

The first would be to actually use one of Debian's packages -- unstable
currently uses gcc 4.0.1 / g77 3.4.*. That seems to work well. You'd get the
same released version for amd64 as well. I'd do that.

The second would be to continue building on your own, but to make sure the
generated Makeconf (which the Debian package copies into /etc/R/) has the
right settings.

Hope this helps, Dirk
