[web-devel] Deploying a yesod app to production, without compiling in production servers.

For security reasons, I would strongly recommend against compiling (or even
having anything remotely resembling a compiler) on your production server.
For that reason, you should probably also leave it off of your staging
server (apt-get remove build-essential) :)
That said, the easiest long-term way to manage binaries in a production
environment is to statically link. If your enterprise is successful,
chances are you'll move on to other products/projects and the older products
will still be running on those machines, but you will have likely upgraded
your development environment (especially when using Haskell) . It is
easiest to minimize your dependencies on .so's. Just my $.02
