linux - build, Derelict and stuff

[freeagle]

Hello,
im having big problems trying to build derelict using build under linux, 
  and im getting clueless more and more :(
First, build tool looks to be strangely configured under linux, when 
trying to build something, it says "dmd/bin/ld : no such file or directory"
When trying to build Derelict, it says "dmd/bin/ar: no such file or 
directory"
actualy, even those scripts for Derelict are not working. It sayd 
command not found. I was trying to dig up something on forums, but im or 
blind or there is nothing about it. Am I missing any libaries in linux?? 
BTW: Im using Ubuntu, 6.06 Dapper Drake

thanks for ANY help
