Trying to build a program from source when it's already in your OS's repository. Oh my goodness do I feel dumb. I really spent quite a lot of time trying (and failing) to this build script to run, including installing a lot of build dependencies I ultimately didn't need.
The funny part is, before I moved on to my netbook I had just installed the same app on my laptop, which I've just put Linux on (Lubuntu, which I love times a million if only because it shares a lot of shortcuts with Windows). I'm so used to ARM Ubuntu getting the short end of the app stick I didn't even try apt-getting it. I was knee deep in troubleshooting this fairly recent install script when figured, if someone wrote a script to automate the build, surely there's a deb or something floating around. I did another web search and found that people were talking about a build target in fact existing for ARM processors.
Side note for future David, why did I install Xubuntu and not Lubuntu on my Chromebook? Surely Crouton has a Lubuntu option. I'll have to look into that the next time I re-stage it.
Then sheepishly, I remembered that I installed it from the repo on my laptop. I typed in the same apt-get string and it worked. I'm assuming it fully worked, but I'm still waiting for some software on the laptop to finish installing. Well, re-installing. System Administration's a pain in the ass if you (meaning me) can't be bothered to remember your (my) password. Yes, this process is relating to my issue with Bittorrent Sync. No, I won't talk about it yet. Not until I actually have something to report.
