snipmate is not working in vim

The following file is my vimrc file. I tried sourcing snipmate.vim file, there is no set paste in my vimrc file. just did a git clone of the snipmate in my .vim directory and added the location to the runtimepath.

I am using MAC OSX

$ cat .vimrc 
source ~/.vim/snipmate.vim/plugin/snipMate.vim
nnoremap <Space> za
vnoremap <Space> za
nnoremap zO zCzO
set smartindent
set hlsearch
set ignorecase
set foldenable
set foldmethod=syntax
syn region foldBraces start=/{/ end=/}/ transparent fold
syn region foldJavadoc start=,/\*\*, end=,\*/, transparent fold keepend
set ai
set sm
set incsearch
set runtimepath^=~/.vim/bundle/ctrlp.vim,~/.vim/nerdtree,~/.vim/snipmate.vim
set nocompatible            " Because filetype detection doesn't work well in compatible mode
filetype plugin indent on   " Turns on filetype detection, filetype plugins, and filetype indenting all of which add nice extra features to whatever language you're using
syntax enable               " Turns on filetype detection if not already on, and then applies filetype-specific highlighting.
set wildignore+=*/tmp/*,*.so,*.swp,*.zip,*.class
set diffopt+=iwhite     "Ignore whitespaces in vimdiff"
filetype plugin on

Other plugins ( ctrl-p and nerdtree ) are working, but snipmate is not. What am I doing wrong?

Solution

You should use pathogen. It does all of this runtimepath stuff for you.
