[Distutils] Limitations of setup_requires

[Joshua Boverhof]

I have a package specified in both "setup_requires" and  
"install_requires", the package is downloaded and used during setup  
but it is never installed in site-packages like the other entry.   
This is happening on both my Mac and a Linux box.

This fails for me with setuptools-0.6c3, python2.5, but works with w/ 
python2.4

Here is what I'm doing:

           install_requires=[
               "ZSI >= 1.2.0rc2", "4Suite-XML >= 1.0rc4",
           ],

           setup_requires=[
               "ZSI >= 1.2.0rc2",
           ],

ssh1:%python setup.py install


Now if I remove it from "setup_requires" and remove the egg  
(otherwise it does nothing):

%rm ZSI-2.0_rc2-py2.5.egg


           install_requires=[
               "ZSI >= 1.2.0rc2", "4Suite-XML >= 1.0rc4",
           ],

           setup_requires=[
           ],


boverhof at pabst(341)-ssh1:%rm ZSI-2.0_rc2-py2.5.egg
boverhof at pabst(342)-ssh1:%rm -rf pyGridWare.egg-info/boverhof at pabst 
(343)-ssh1:%python setup.py install --force

It now installs.

Reading http://www.python.org/pypi/ZSI/2.0-rc2
Best match: ZSI 2.0-rc2

Adding ZSI 2.0-rc2 to easy-install.pth file


Has anyone else noticed this behavior?
