unable to build your site

[eleni-xar]

Hi,

I have been able to use Hakyll successfully for simple sites using the initial examples, but I wish to build something more interesting. I've tried to look at some realistic examples, but so far none of the examples I've tried have yielded a working website.
I wanted to use your site as a demonstration. Unfortunately, it doesn't build for me. Here are my steps:

$ stack build
$ stack exec jaspervdj build

the build ended with the following:

Could you please point out what's missing?

My website (unfortunately) depends on a few tools that need to be installed. Off the top of my head, those are:

• xelatex (and some fonts maybe)
• convert (from ImageMagick)
• dot (from GraphViz)

I think the build is failing on your machine because one of these is missing.
