pydev调试器:在OS 10.8升级后无法找到python 2.7的真实位置

我刚刚升级到OS X 10.8 Mountain Lion，并在理解pydev调试器在Aptana 3.0上的工作方式上遇到了麻烦.

I just upgraded to OS X 10.8 Mountain Lion and having troubles understanding how the pydev debugger should work on Aptana 3.0.

在Aptana的首选项中，我具有python解释器设置，其位置为"/usr/bin/python".它指出系统库来自"/System/Library/Frameworks/Python.framework/Versions/2.7/..."

In Aptana's preferences I have the python interpreter setup with a location of "/usr/bin/python". It states that the System libs are coming from "/System/Library/Frameworks/Python.framework/Versions/2.7/..."

当我在Aptana中启动我的Google App Engine项目的调试器时，控制台会记录:

When I start the debugger for my Google App Engine project within Aptana, the console logs:

pydev debugger: CRITICAL WARNING: This version of python seems to be incorrectly compiled (internal generated filenames are not absolute)
pydev debugger: The debugger may still function, but it will work slower and may miss breakpoints.

它还指出:

pydev debugger: Unable to find real location for: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py
pydev debugger: Unable to find real location for: /Applications/Aptana Studio 3/plugins/org.python.pydev.debug_2.2.2.2011100512/pysrc/pydevd.py
pydev debugger: Unable to find real location for: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.py
...

它列出了"/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/"文件夹中的所有.py文件.

And it lists out all of the .py files within the "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/" folder.

我的App Engine项目仍在加载，但我真的不明白为什么.我需要配置Aptana 3.0，在OSX 10.7和10.8之间进行了哪些更改，从而使此严重警告出现?

My app engine projects still loads, but I don't really understand why. What do I have to configure Aptana 3.0, and what's changed between my OSX 10.7 and 10.8 that made this critical warning come up?
