Spiderable: phantomjs failed: null

I've been trying to figure out the problem with a lot of hours for hours. I installed it and it worked nicely on my local machine, but as soon as I deploy to production I get this error spiderable: phantomjs failed: null

. As you can see, this is not very helpful when debugging the problem.

I followed all the advice in this excellent post on Meteorpedia, to no avail: http://www.meteorpedia.com/read/spiderable/

To make it even weirder, when I run the phantomtest.js

script I found on the page above everything works without any problem.

What I really would like to do is log some debug output from PhantomJS as it is called spiderable, but I have no idea if this is possible. I tried messing up the code with the extension to pass some additional debug options to PhantomJS, but that didn't work for me.

Any input is greatly appreciated.
