Scons: I fail to add qt4 tool

I followed the following guide to the letter:

http://www.scons.org/wiki/ToolsIndex

I tried checking out lp:scons-qt4 in:

1. Directory with a project

2. ~/.scons/site_scons/site_tools

3. ~/.scons diretory

But a simple SConstruct file with a line:

env = Environment (tools = ['default', 'qt4'])

Still produces an error message:

scons: Reading SConscript files ...
EnvironmentError: No tool named 'qt4': 开发者_JAVA技巧not a Zip file:
  File "/home/septi/Документы/ScanModule/SConstruct", line 3:
    env = Environment (tools = ['default', 'qt4'])
  File "/usr/lib/scons/SCons/Environment.py", line 991:
    apply_tools(self, tools, toolpath)
  File "/usr/lib/scons/SCons/Environment.py", line 105:
    env.Tool(tool)
  File "/usr/lib/scons/SCons/Environment.py", line 1691:
    tool = SCons.Tool.Tool(tool, toolpath, **kw)
  File "/usr/lib/scons/SCons/Tool/__init__.py", line 94:
    module = self._tool_module()
  File "/usr/lib/scons/SCons/Tool/__init__.py", line 154:
    raise SCons.Errors.EnvironmentError(m)

So, what am I doing wrong? Maybe it's not supported in my version or something? I'm totally puzzled and don't know where to start.

I'm running Ubuntu 10.10, scons version is 2.0.0.final.0.r5023.

Adding a tool to the .scons directory in your home was only a recent addition - you need to be using SCons 2.1 or later.

If you want to use the qt4 tool within a project, then you have to add it to <project>/site_scons/site_tools/. As you use the tool as "qt4", then the sub-directory must be called "qt4" within the site_tools directory. It can't be called "scons-qt4" or anything else, which may depend on the options you pass to bzr when you check out the project from launchpad.
