Building SDL_image (from mercurial) on Ubuntu 12 with acloca

Just to make this more clear for anyone else who may run into this and google this thread.

If, after setting up a build folder, and running …/configure within the build folder, you get a single error when running make saying:
SDL_image: cannot find autogen-1.13 blah blah

Be sure to get the automake and autoconf packages (sudo atp-get install automake autoconf)

Then you need to go back to the root directory and run ./autogen.sh

You should be all set!
best of luck
