can't add panel for histogram

[cleesmith]

If I git clone https://github.com/elasticsearch/kibana.git
then cd src
then python -m SimpleHTTPServer
all is fine, except I can't click on Add Panel for Histogram
with or without all of the options filled.

Yes, it works in the zip file download, but I wanted to make some
changes/enhancements.

Ideas or suggestions ?

UPDATE: after doing this:
a)Install node & npm
b)npm install -g grunt-cli
c)npm install <--- in the kibana folder
d)grunt build
... the Add Panel button is now clickable, but for any options/settings no data shows just a spinner.

Thanks.

Apologies, I forgot to git checkout tags/v3.0.0milestone4 ... master is broken but this works just like zip download.
