XORP installation

Hi everybody!
I am trying to install xorp 1.1 on my pc...i have a Linux O.S with a debian distro on a 2.4.21.click kernel.
After i completed xorp installation sucessfully i tried to run the xorp bash(xorpsh),using the config.boot.sample file as my boot file but some errors occured.
I checked it out and i found that there were still some problems while xorpsh was trying to run xorp_rtrmgr application so i tried to exucute this last file but there were some problems again.
Here there are the error body texts:

Could anybody help me to solve this problem.
Thanks a lot in advance.
