The installation in itself was OK, though I found the "Installation successful" messages a bit disconcerting. Maybe you should consider an installation log file or a longer message to tell what exactly was installed, in which directory, and suggest some starting points for beginners.
Concerning the utilization now : I have two python 2.6 installed on my computer though I do not remember nor why nor how. The default python (the one that runs when typing "python" on the command line) links to /Library/Frameworks/Python.framework/Versions/2.6/bin/python (it claims to be a v2.6.4 compiled with gcc 4.0.1 ) My second python dwells in /usr/bin and claims to be a v2.6.1 compiled with gcc 4.2.1
With the first interpreter, IMP is not automatically found and I have to modify the PYTHONPATH (therefore the localization of IMP in the installation message could be of interest.). When this is done, the package is found but any attempt to use it results in an error : Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.6/site-packages/IMP/__init__.py", line 25, in <module> _IMP = swig_import_helper() File "/usr/local/lib/python2.6/site-packages/IMP/__init__.py", line 17, in swig_import_helper import _IMP ImportError: dlopen(/usr/local/lib/python2.6/site-packages/_IMP.so, 2): no suitable image found. Did find: /usr/local/lib/python2.6/site-packages/_IMP.so: mach-o, but wrong architecture
With /usr/bin/python the IMP package is automatically detected, and everything runs fine.
In order to explain the problem observed with the default interpreter, I firstly suspected it had something to do with the gcc version, but now I rather think it is a 32bits/64bits conflict :
