I am new to python and programming in general.
I want to download the python gtk library in order to do some interacing with my arduino. My question is, is it normal for this installation to take so long? Also, did I do it right? And if I screwed up, how can I uninstall this and fix the issue.
As instructed by my textbook, "Make: Arduino Bots and Gadgets," I downloaded macports (which works fine. I have tested it with man ports). But then I tried to use the command the book provides to download the gtk library: sudo port install py-gtk2. This code did not work. I did some research (sorry, I lost the link where I found the code), which told me to input sudo port install py27-pygtk. I pasted that into my terminal about an hour ago, and now there are about 33,000 lines of code being printed in my terminal. I've included the beginning and end of this printout below. The terminal has been stalled at the line `building libgcc for about 20 minutes.
BTW, I am running python version 2.7.9
$ sudo port install py27-pygtk

Yes, this is normal if you don't have anything else installed via MacPorts. port doesn't just install the package you specify, it also installs all the dependencies, and their dependencies, etc. etc. Since it builds a number of packages from scratch, GCC is required. Let it go for a while, as building everything takes a good amount of time, depending on the specs of your computer. If it seems to be stuck on a particular step for an hour or so, though, probably something has gone wrong. Hit CtrlC, then run your previous command again. As you can see from the "Dependencies" line, a rather large list of packages (90 of them) need to be downloaded, built, and installed (I sorted them alphabetically):
