build stalls on install/update GYP

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Checkout the most recent version of the code from 
http://pyv8.googlecode.com/svn/trunk
2. In the code root directory, run python setup.py build

What is the expected output? What do you see instead?
Build should complete and terminate, instead it gets to the step where the 
output reads 
"INFO: Check out GYP from SVN ...
DEBUG: > make dependencies"
and hangs indefinitely, and htop does not indicate that it is working (this was 
allowed to continue 'running' for several hours.

What version of the product are you using? On what operating system?
r586 on Mac OS X Yosemite 10.10.3

Please provide any additional information below.
I am attempting to install this in order to enable additional JS analysis 
functionality in peepdf to gather info on potential malicious PDF files.
