Re: Big problems with scientifc use of amd64

    I use Debian testing/unstable for very very scientific work and I know the 
problem you are describing.

The solution I use on several computers is to run everything I can under 
testing/unstable and then create chroot for programs that need older versions. 
I have installed Sarge (i386) RedHat enterprise, Lenny (386 and amd64) on the 
same amd64 computer in order to get everything working.

Hope it works for you
