I'm using Debian 2.2 distribution and have a piece of commercial software from Novell that won't install unless it has the following file ... libstdc++-libc6.1-1.so.2 I've had a look at this distribution and Debian 2.2 uses libstdc++-libc6.1-2.so.3 Is it possible to go backwards and am I likely to break anything? If I cannot go backwards should I start with the 2.1 distribution and work my way up? Thanks Craig
