PhantomJS: getting "Killed: 9" for anything I'm trying

Just installed phantomjs, mac os x yosemite. Whenever I run /bin/phantomjs, with any parameter, I get Killed: 9. Any idea?

1. Install UPX. UPX is an executable packer and unpacker

   $ brew install upx
   

2. Unpack the phantomjs executable

   $ upx -d phantomjs-2.0.0-macosx/bin/phantomjs
   

3. Run the phantomjs executable

   $ ./phantomjs-2.0.0-macosx/bin/phantomjs
   

re: running phantomjs on osx yosemite, download the build/fix found at:

The eugene1g release and UPX install didn't work for me on El Capitan. What did work for me was installing PhantomJS using the phantomjs2 NPM package:

npm install phantomjs2

# Optional: symlink in a dir that's on my PATH:
ln -s /usr/local/lib/node_modules/phantomjs2/lib/phantom/bin/phantomjs /usr/local/bin/phantomjs
