replacing xftpd with vsftpd

All,

I am in the process of replacing xftpd with vsftpd on 10.4.10 Server for preformance and stability reasons. However, I am having a heck of a time getting it to run via launchd. (too many years in xinetd i guess...) I was hoping that someone could give me a hand or atleast a point in the right direction.

Below is my config file (ftp.plist):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.gnu.vsftpd</string>
<key>ProgramArguments</key>
<array>
<string>vsftpd</string>
</array>
<key>Sockets</key>
<dict>
<key>Listeners</key>
<dict>
<key>SockPassive</key>
<true/>
<key>SockServiceName</key>
<string>ftp</string>
<key>SockType</key>
<string>SOCK_STREAM</string>
</dict>
</dict>
<key>UserName</key>
<string>root</string>
<key>inetdCompatibility</key>
<dict>
<key>Wait</key>
<false/>
</dict>
</dict>
</plist>

And whenever I attemp to the ftp server i get the following error.
launchproxy[461]: execv(): No such file or directory

However cannot get past that point. Any help you can provide would be great.
