Hmm, you're right. I ran nodeJS just fine and see the same errors.
I wonder _what_ exactly is causing the nix-env program to not run
all the way. When I run it, I get these errors in the STDOUT:
GC warning: pthread_setname_np failed
error: setting death signal: Function not implemented

When I look through the ktrace of nix-env, I don't see anything
obvious. It might be that I just don't know what to look for too.
Do you have any general rules of thumb when looking at this sort
of thing?
