Install has been sitting on the dependency step for twenty minutes — stuck or slow?

On the VPN, laptop otherwise idle. The installer printed the dependency install step and has produced nothing since. No error, no progress, cursor still blinking.

I re-ran it with --verbose and now I can see it is doing something, but it is crawling and I cannot tell whether it will finish or whether I should kill it and start over.

sh install.sh --verbose

Is there a point at which I should assume it is wedged? I would rather not interrupt it halfway if re-running is worse than waiting.
