SVNADMIN command not responding

Hi All,
I am new using svn. I was told to create a svn repository.

i executed the following command and confirmed that svn is working in the machine.(tell doing do is correct)

>svn help

it listed many subversion commands.Then i did the following

>mkdir /home/maectest/svn
>svnadmin create --fs-type fsfs /home/marctest/svn
-ksh: svnadmin: not found [No such file or directory]

What should i do now to create a SVN repository? What should i check in installations?

If you want to run a command, it has to be on the host, executable to you and in your $PATH or called with supporting path. Did you install your own svn?
