That's fair. Pex does support specifying a target platform though, which can package linux binary dependencies on a Mac for example. That being said, if a native dependency doesn't provide binaries (i.e. source only) we're out of luck. We solve this issue by precompiling and publishing those dependencies on a private package index. Thankfully there are only a handful of dependencies that need this.
