GDC on psptoolchain

[John Grindstaff]

To clarify, I try to enter the gcc-4.1.0/gcc/d/phobos directory and do 
./configure but I get this:
configure: error: cannot find install-sh or install.sh in . ./.. ./../..
So I'm not exactly what to do. If I put a blank install.sh file I get 
this error:
configure: error: cannot run /bin/bash ./config.sub
