svn problem...

I've been trying to compile MPlayer, and that requires me to do a subversion to mplayerhq.hu but by doign an svn to mplayer.hu, i get a command not found. error

CPE0016cb90d01a-CM0011e67a34b1:~/Development/mplayer-src novey$ svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
-bash: svn: command not found

At first i thought subversion isn't installed, so I went and install subversion, from http://metissian.com/projects/macosx/subversion/

But after installation (well actually it seems like svn is already installed in my OS anyways, since all it did was ask me whether i want to upgrade it), so after I've upgraded it, it still give me the same error.

Any idea what's wrong?
