This is already broken with source dists if you don't have the appropriate
-dev packages (or a compiler) installed. Some package authors provide more
useful feedback explaining what the problem is and how one might resolve
it, rather than dying on a compiler error due to a missing header, but many
One solution to this for both source and binary distributions is package
manager awareness in the build/install tools, and to have packages declare
their dependencies in structured metadata. A translational layer would make
this easier on package authors: If they only had to say they depend on
"OpenSSL headers" and that was translated to the correct package for the
OS, this could be relayed to the user at build time ("install these
packages using this command") or the package manager could be directly
invoked, if the user has chosen to allow the build/install tool to do that.
