> I timed @time Pkg.add(“InteractiveDynamics”) this morning. Agree with Tim Holy on the time. I can repeat and give exact time. This is on a laptop running Fedora. Are you very constrained in resources on your machine? Maybe low on rAM and swapping is happening?

This is twice we have a report of very large compilation times. Are we seeing the start of a common problem?

I suspect this is not a bug in Julia, rather that these systems are swapping due to large memory use. Thats just a wet finger stuck up to test the wind of course.  
Please report versioninfo()
