Hi all,

I have learned (thanks to the el-get developers) that org-mode uses
with-eval-after-load, which was added in Emacs 24.4. (See discussion [1].)

I confirmed that the master branch of org-mode loads (via el-get)
successfully in 24.4.1 and fails to load in 24.3.1.

I'm not sure what the compatibility policy is in this project, and whether
or not this deserves a fix. I personally can work around this by building
Emacs from source on older machines, but I will need to do this on every
Ubuntu 14.04 machine I use.
