Can´t build

Hi, I can´t build Kibana 4.3.1 in Ubuntu 14.04, when running "npm run build" I get bellow errros. Aside of this (very odd) if I run with --force it fails few steps before, in _build:installNpmDeps task because a github time out trying to fetch jquery, which is working fine from command line! Any Idea?

Running "_build:downloadNodeBuilds:finish" task
Warning: unexpected eof Use --force to continue.

Aborted due to warnings.

Looks like it is unable to download the node.js binaries... Maybe running with the --verbose flag will shed some more light on the issue.

npm run build -- --verbose
