It is clear that building on CentOS 5.7 is not possible with the distribution, however is a possibility with some customization and source installs outside of the available system packages. Python3.1+ is a big worry on CentOS because it can potentially break and obliterate the package manager if not done carefully.

Anywhow, perhaps the issue is truly a documentation issue, or best left that way, the bind10-guide.txt states GCC 3.4.3+ when I think maybe it is better to say 4.3.(?) + 
Perhaps a typo.. dunno.
Otherwise I don't see how it's going to happen to build boost with -Werror .. The bind10 code does not appear to produce warnings, it's a boost issue. The workaround mutes the warnings but there's the unknown problems that might happen with improper binary.
Thanks!'
