Question about installing ppmtomd port

[KT]

I noticed that MacPorts now has the ppmtomd port, so I tried  
installing it via>

sudo port -v selfupdate
then
sudo port install ppmtomd

But returned an error message. (message pasted at end  of email)
I have MacPorts 1.600, and 10.4.11 on the macbook I'm trying to  
install ppmtomd on.
Anyone know what the problem may be?  Does this port package only  
work on 10.5.X?

Thanks in advance.

Kory
