Because this is a bizarre argument. I accidentally make dependencies on specific variants of libraries because I don't immediately need to support other variants and lack examples and/or time to worry about theoretical portability.

I don't use OS specific packaging because it was intentionally written to be non-portable. My learning it is an irrational commitment to keep using an OS at the neglect of all others and even if its distributor changes (or can no longer honor) the conditions of our deal.

Your dynamic website (often called a webapplication) is very probably OS-specific anyway. I've seen websited that can run only on Ubuntu. Most often you could as well settle with what OS provides to deploy it, especially that you won't need another instance on the same server. Even more so if it's not a hobbyst project, but a professional one.

Only if you use it mindlessly. It's not really different to build a package for Debian, Red Hat, Slackware, or Gentoo (been there, done all of these). All it takes is to properly separate downloading sources and building things, which is a good engineering on its own. And guess what you get in exchange? Easy dependency installation, both for development and for deployment.
