OSX install requires Python 2.7

[jerith]

When I try to install node.js on OSX 10.6 (which has Python 2.6.1) I get the following build error:

  rm -f /private/tmp/node-g9y1/node-v0.10.24/out/Release/libhttp_parser.a && ./gyp-mac-tool filter-libtool libtool  -static -o /private/tmp/node-g9y1/node-v0.10.24/out/Release/libhttp_parser.a /private/tmp/node-g9y1/node-v0.10.24/out/Release/obj.target/http_parser/deps/http_parser/http_parser.o
  File "./gyp-mac-tool", line 507
    return {k: self._ExpandVariables(data[k], substitutions) for k in data}
                                                               ^
SyntaxError: invalid syntax

The dict comprehension syntax was introduced in Python 2.7, which means this code path fails on Python 2.6. The line that failed above could easily be replaced with some like return dict((k, self._ExpandVariables(data[k], substitutions)) for k in data) but there would probably need to be a deeper audit of the Python code to make sure Python 2.6 is supported in all cases.

Should be fixed by #6861

May I ask you to give it a try?

A very similar fix does work for me, but it seems this is the kind of thing that should be fixed upstream.
