I recently had to build gcc 4.6.2 on CentOS 5.5 and found it to be quite painful so I put together this script to do all of the work: http://projects.joelinoff.com/gcc-4.6.2/bld.sh.txt. I am releasing it in text mode so that you can cut-n-paste it from the web page.
The shell version is also available: http://projects.joelinoff.com/gcc-4.6.2/bld.sh if you want to download it directly using something like wget.
