Should you use a precompiled binary distribution (e.g., RPM, tgz, etc.), or should you compile BIND from source?

For most users, it's perfectly acceptable to use a binary distribution, provided it comes from a trusted source. Virtually all Unix variants include BIND with their "stock" installations; just be sure to verify that you've indeed got the latest version.
