Installing Vim from source on Ubuntu to fix crashing

gistfile1.sh

# The vim included with Ubuntu Natty is heinously buggy.  Also Lucid it appears.
# Fix that by compiling the latest Vim 7.3 yourself:

sudo dpkg --purge vim-runtime vim-gui-common vim-gtk vim-gnome vim-nox
cd vim/src
sudo apt-get install mercurial libgnome2-dev libgtk2.0-dev libatk1.0-dev libbonoboui2-dev libcairo2-dev libx11-dev libxpm-dev libxt-dev libperl-dev python-dev ruby-dev
hg clone https://vim.googlecode.com/hg/ vim
rvm use system     # (if you're using rvm)
./configure --enable-perlinterp --enable-pythoninterp --enable-rubyinterp --enable-cscope  --with-features=huge --enable-gui=gnome2 --with-x
make -j 3          # 3 jobs in parallel, 1 more than # of cores
sudo make install
sudo ln -s /usr/local/bin/vim /usr/local/bin/vi

# Done!  Now your vim won't crash when you invoke Command-T or Hammer.


# If vim still crashes and you use rvm, you need to do this to ensure
# that vim is running against the system's ruby:

sudo mv /usr/local/bin/vim /usr/local/bin/vim.orig
sudo tee /usr/local/bin/vim << 'EOL'
#!/bin/bash

if type -t rvm >/dev/null 2>&1; then
  exec rvm system exec -a "$0" vim.orig "$@" 
else
  exec -a "$0" vim.orig "$@"
fi
EOL
sudo chmod a+x /usr/local/bin/vim

It appears that all this mess is to work around rvm. rbenv doesn't suffer the same problem. If you compile Command-T against system Ruby, everything just works.
