It seems to me that if a given distro can be built either with a compiler or without one (e.g. Params::Validate), then the answer to "does it require a compiler" is a simple "no".
Only if that "either" is across all platforms.
If something, for example, was looking for /proc/ files on Linux, but needed to compile some Win32 dep module on Windows, the the answer isn't a simple "no", it's a "maybe" (at least in META.yml).
