Alex Clemmer commented on MESOS-5145:
-------------------------------------
This is only true on Windows. On Unix it is possible to build out of the
rebundled dependencies, and if you choose to use dependencies that are not
rebundled, then you can point CMake at a local folder containing the tarballs.
On Windows, we have to rope in all the dependencies we normally expect the
package manager to take care of, like cURL. So we unfortunately still do go to
network. Or, this was true last time I checked.

> Updating [protobuf from 2.5 to
> 2.6.1|https://github.com/apache/mesos/commit/51872fba7f94d80e55c9cc9b46f96780a938f626]
> has caused Mesos builds to fail if pypi.python.org is unreachable.
> Protobuf-2.6.1 requires
> [google-apputils|https://pypi.python.org/pypi/google-apputils] and if it's
> not available the build process will attempt to download it from pypi.
> Prior to this change it was possible to build Mesos without Internet access.
> If the build process reaches out to arbitrary things on the Internet it's
> impossible to guarantee build reproducibility.
