I have Mac OS 10.8.2, Python 2.7.3, Xcode 4.5.1.
I am trying to install portaudio (so that I can use import pyaudio in python) following the instructions in http://www.portaudio.com/docs/v19-doxydocs/compile_mac_coreaudio.html.
As mentioned in the site, I downloaded MacOSX10.4 SDK from http://connect.apple.com, which downloaded as DMG file. I installed it successfully. But MacOSX10.4.sdk never got itself placed it in the path Applications/Xcode.app/Developer/Platforms/MacOSX.platform/Developer/Library/SDKs, along with MacOSX10.7.sdk and MacOS10.8.sdk. Considering its unavailability, ./configure && make shows error.
Here is a screenshot of the folder

How do I solve it?
I would just install it using homebrew. I am running MountainLion and it installed in 14 seconds.
