I am on Ubuntu, and my copy of julia was installed with apt-get install julia.
I was trying the curve fitting tutorial found here ( http://www.walkingrandomly.com/?p=5181) but I kept getting the error "curve_fit not defined". Yes, I have done "Pkg.add("Optim")" and "Pkg.add("LsqFit")", that doesn't help. Apparently, nobody else on the internet has ever had this problem. <https://www.google.com/search?client=ubuntu&channel=fs&q=%22curve_fit+not+defined%22&ie=utf-8&oe=utf-8>I'm surprised. Also, it doesn't seem like I can find the version number of Julia that I'm using. Following this (http://stackoverflow.com/questions/25326890/how-to-find-version-number-of-julia-is-there-a-ver-command) just gives me the error "verbose not defined". Is every piece of documentation about Julia from earlier than 6/2015 invalid now? The responses I found here <https://groups.google.com/forum/#!topic/julia-users/djWGrU6z3Hc>are pretty useless, as curve_fit doesn't even work by itself.
