Installing PHP on OS X. Syntax errors?

When installing OS X on Yosemite with curl -s http://ift.tt/1mfZO8d > install.sh, I get the following:

****
[WARNING]
Detected OS X Yosemite 10.10. As this is quite new, there may be issues still. Your mileage may vary.
****
Get packager.tgz
Unpack packager.tgz
Please type in your password, as we want to install this into /usr/local
Start packager (may take some time)
  File "/usr/local/packager/packager.py", line 38
    print "ERROR: Option %s is not valid for command %s\n" % (opt[0], command)

Is this truly a Bash syntax error? It looks like a normal Bash statement to me. What am I missing?
