Subversion is not working !

Dear all,
I'm trying to install/update Textmate's bundles using svn. When I try with the following instructions in terminal:

$mkdir -p /Library/Application\ Support/TextMate/Bundles
$cd /Library/Application\ Support/TextMate/Bundles
$svn co http://svn.textmate.org/trunk/Bundles/Haskell.tmbundle

I'm getting the following error(s):

svn: PROPFIND request failed on '/trunk/Bundles/Haskell.tmbundle'
svn: PROPFIND of '/trunk/Bundles/Haskell.tmbundle': Could not resolve hostname `svn.textmate.org': Host not found ( http://svn.textmate.org)

I don't know where I'm doing wrong. Please help me out. Thanx.
