I needed to install vim with lua support because I wanted to use neocomplete in my recently installed 15.04 distro. Also, this has python3 enabled by default.

Tested on 16.04 now

Update: This has been tested and verified to work on Ubuntu 16.04 as well. Also, if you wish to use particular branch/tag, you can get the version and then checkout appropriately.
The following (based upon https://gist.github.com/jdewit/9818870) should work though I copied it from history:

sudo apt-get remove --purge vim vim-runtime vim-gnome vim-tiny vim-common vim-gui-common
sudo apt-get build-dep vim-gnome
sudo apt-get install build-essential liblua5.3-0 liblua5.3-dev python-dev ruby-dev libperl-dev libncurses5-dev libgnome2-dev libgnomeui-dev libgtk2.0-dev libatk1.0-dev libbonoboui2-dev libcairo2-dev libx11-dev libxpm-dev libxt-dev

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.
