First error. Building Basic GUI tutorial

[Giuseppe Luigi Punzi]

Hi all again,

I finish the Basic GUI tutorial(1), and I'm having troubles building it.

On my work machine(2), I installed GNUstep-System and GNUstep-Core 
0.22.0 and Gorm 1.2.8, and from the msys shell, compiled Project Center 
0.50 without troubles. I started to code the tutorial, and all was good, 
until I was to build.

When I try to build, I get the next error:
Build Terminated
Build Tool not found.
File "<NSArrayEnumerator: 0x1ed9b58>" doesn't exis!

I can suppose, some command tool is missed. But, I installed all the 
packages, and, ProjectCenter for example, was builded ok.

I'm missing something?
