After fussing with the instructions and having no luck, I finally figured something out.  After compiling wxWidgets 2.9.3, flam3, and Electric Sheep v2.7b33, I was getting a black screen with a white box/square in the center.  I left it running and still nothing changed.  Also, I had a problem where the preferences were not storing or loading any changes I made.  After running electricsheep-preferences from CLI this last time, I noticed it output the following line:

"SetInstallation: /usr/local/share/electricsheep/Scripts"

So I went to this directory and behold, there was no "Scripts" folder.

To fix this, I went back to the "electricsheep-read-only" folder (which was in my Downloads folder), and snooped around a bit.  I noticed that the contents of the "client_generic/Runtime" folder match the contents of "/usr/local/share/electricsheep/", only it had a "Scripts" folder with content inside it.

I copied the "Scripts" folder from here into "/usr/local/share/electricsheep/" and re-ran "electricsheep-preferences".  I was now able to login!  I launched "electricsheep-preferences" again and now my changes save and load properly.  After making some quick changes, I relaunched "electricsheep".  SUCCESS!  IT WORKS NOW!

So, bottom line, below is exactly what I did on Ubuntu 11.10 to successfully get the newest Electric Sheep to work on my system.  I broke the steps down to the smallest steps:

1. sudo apt-get install subversion autoconf libtool libgtk2.0-dev libgl1-mesa-dev libavcodec-dev libavformat-dev libswscale-dev liblua5.1-0-dev libcurl4-openssl-dev libxml2-dev libjpeg8-dev libgtop2-dev libboost-dev libboost-filesystem-dev libboost-thread-dev libtinyxml-dev libglee0d1 freeglut3-dev glee-dev
2. cd ~/Downloads
3. wget http://superb-dca2.dl.sourceforge.net/project/wxwindows/2.9.3/wxWidgets-2.9.3.tar.bz2
4. tar jxvf wxWidgets-2.9.3.tar.bz2
5. cd wxWidgets-2.9.3
6. ./autogen.sh
7. ./configure
8. make
9. sudo make install
10. cd ~/Downloads
11. svn checkout http://flam3.googlecode.com/svn/trunk/ flam3-read-only
12. cd flam3-read-only/src
13. ./configure
14. make
15. sudo make install
16. cd ~/Downloads
17. svn checkout http://electricsheep.googlecode.com/svn/trunk/ electricsheep-read-only
18. cd electricsheep-read-only/client_generic
19. ./autogen.sh
20. ./configure
21. make
22. sudo make install
23. HERE'S THE FIX: sudo cp -r Runtime/Scripts /usr/local/share/electricsheep/
24. electricsheep-preferences
25. Configure as needed, then click "OK"
26. electricsheep
27. Voila!  It works!

Now just configure xscreensaver to use electricsheep and you're done!

1. sudo apt-get remove gnome-screensaver
2. sudo apt-get update && sudo apt-get install xscreensaver xscreensaver-gl-extra xscreensaver-data-extra
3. Press Super key (Windows key) and type Startup.  Select Startup Applications.  Click "Add".  Enter the following:
4. Name: XScreensaver
5. Command: xscreensaver -nosplash
6. Click "Save"
7. Click "Close"
8. In Terminal: gedit ~/.xscreensaver
9. At the bottom of the file, add (Without quotes): "GL: electricsheep --root 1 \n\"
10. Click "Save" and exit gedit.
11. Done.
