Why orocos give me this error(Ubuntu 8.04,RTAI 3.6)

As my system is ubuntu, so I do install things following:

$ cd src
$ sudo apt-get update
$ apt-get source orocos-rtt
$ sudo apt-get build-dep orocos-rtt
$ sudo apt-get install devscripts build-essential fakeroot dpatch
$ cd orocos-rtt-1.4.0
$ dpkg-buildpackage -rfakeroot -uc -us
$ cd ..
$ for i in *.deb; do sudo dpkg -i $i; done

But when I do "sudo apt-get build-dep orocos-rtt", it gives me error:
"
E: Package xenomai-dev has no installation candidate
E: Package xenomai has no installation candidate
E: Failed to process build dependencies
"

I know xenomai is another RT linux system and I have not installed it on my
system as I have RTAI.

Why do I need this?
I try install xenomai-dev, but it still gives me that errors..

so strange things, are there anybody have the same problem?

Even if you don't want to use Xenomai, you need to provide it because we build
Debian packages for gnulinux, rtai and xenomai in one run.

We're pulling xenomai from Debian testing or unstable. See also

In case it is an error in package names, edit orocos-rtt-1.4.0/debian/control
and rename the xenomai dependency to the package you have installed.
