Hi Robin,
I downloaded your latest development build for Mac. The cocoa version for Python 2.7. The dmg file opened fine. However, when I click on the package to run the installer I get a message that the package is corrupted - see attachment.
My environment:
Mac OS X 10.8.4
Python 2.7.5 64bit version from python.org

Not to be rude, but did you delete the old file and redownload? I’ve encountered this problem a couple of times, and I find redoing the download for whatever reason seems to get a clean copy.

It's working here with a freshly downloaded copy of the .dmg. Please redownload it and try again. Also ensure that you have "Allow applications downloaded from:" set to Anywhere in the Security system preferences.

I think the exact text is “damaged”, rather than “corrupted”. I see the same thing on my OS X 10.8 machine.
This message is coming from GateKeeper (OS X 10.8’s security watchdog). This message usually means that the package has been digitally signed, but then the package was modified after it was signed, invalidating the signature.
But in this case, GateKeeper is unable to look up the package’s CFBundleIdentifier in:
wxPython2.9-osx-cocoa-py2.7.pkg/Contents/Info.plist
because this file (which GateKeeper expects to find) is missing from the PKG.
The digital signature which GateKeeper is looking for is associated with the package’s CFBundleIdentifier, but without an Info.plist, GateKeeper can’t find the package’s CFBundleIdentifier.
The workaround suggested by Robin (using “Allow applications downloaded from Anywhere”) works for me. After you have opened the PKG, you can change your Security setting back to the default if you wish.
Running the following tells me that the PKG is invalid (by OS X 10.8’s standards):
$ spctl --assess --type=execute --verbose=4 /Volumes/wxPython2.9-osx-2.9.5.0-cocoa-py2.7/wxPython2.9-osx-cocoa-py2.7.pkg
/Volumes/wxPython2.9-osx-2.9.5.0-cocoa-py2.7/wxPython2.9-osx-cocoa-py2.7.pkg: bundle format unrecognized, invalid, or unsuitable
If I run the same command on a valid PKG, (which is not digitally signed), I see:
$ spctl --assess --type=execute --verbose=4 /Volumes/Python\ 2.7.5/Python.mpkg
/Volumes/Python 2.7.5/Python.mpkg: rejected
source=no usable signature
Cheers,
James
