Python support is needed by vim in order to run things like Conque and Slimv. Arch keeps vim slim by only providing Python support in gvim. But you may prefer vim to gvim, so here's what's needed.
# Install and run abs (sync)
sudo pacman -S abs
sudo abs
# Prepare a build area
mkdir ~/abs
cd ~/abs
# Make a local copy
cp -r /var/abs/extra/vim .
cd vim
vim PKBGUID
# Change the --disable-python options to "enable"
# Build the package
makepkg
# Wait for a while
# Install your new vim and runtime
sudo pacman -U vim-runtime-7.3.547-1-x86_64.pkg.tar.xz
sudo pacman -U vim-7.3.547-1-x86_64.pkg.tar.xz
# Check it for "+python"
vim --version
Also, if you're running on 64-bit arch, you may get this error:
To fix: run
makepkg
as soLD_LIBRARY_PATH=/usr/lib/:/usr/lib32 CC=gcc makepkg
. This allows it to pull 32 bit libraries if need be and sets the default compiler to gcc (clang is stricter and may throw errors).
