Solution:
Change PATH environment variable. (You can change it for vim runtime and keep the original one in other programs. See my newer post for details.)
It's a small syntax error, and can be easily fixed with the addition of a space character. I found it from a Google search result. (I've forgotten the query string.)
This shows to good things of free and open source software:
Find bugs quickly through effective communication between users and developers
Fix bugs quickly through hands-on configuration of source code
From the Vim plugins in the GitHub, you can see even more:
Everyone can tune the software to adapt to his/her needs.
Everyone can share and contribute their changes.
and more ...
The more the developers, the further they can see!
With the Vim-$\rm \LaTeX$ plugin, it's possible to edit $\rm \LaTeX$ equations with Vim quickly without making syntax errors. (e.g. undefined control sequence caused by mismatched braces '{}')

Why use Vim? Please refer to my post on Vim.
For a quick startup guide, see the official tutorial. If you've learnt those keyboard mappings, here's a quick review of some commands. For detailed list of all keyboard shortcuts and customizations (e.g. custom compile rule: use pdflatex instead of latex and dvipdfm), you can refer to the user manual.
There're many blog entries about how to install $\rm \LaTeX$ on Vim/GVim on UNIX/Linux and M$. Searching "vim latex" gives you millions of search results. Summarizing the articles, the three major components are:
Editor
Vim (found on almost every distribution of *nix)
GVim (on GUI of any platform)
$\rm \LaTeX$
$\rm \TeX \text{Live}$ (found in package manager on *nix)
$\text{Mik}\rm \TeX$ (have a $\rm \LaTeX$ package manager)
Vim plugin for writing $\rm \LaTeX$: Latex-Suite
For *nix, you may find some GUI tools for installing packages. (especially in some popular distributions)
