Yeah, I'm following those to the letter, but I think that's my issue is, there might be a step missing because when compiling bitcoin, the errors point towards something else missing in the wx2.9 stuff (maybe an additional step) necessary. I think I'm close to figuring it out, if I do, I'll be sure to post it and hopefully have the text updated for future people to avoid any frustration 
You downloaded all the dependencies too? I know I had a bunch of problems until I did that. Good luck, I've done it myself so it's definitely possible.
