TikZ does not work with ConTeXt

[Felix Krause]

After installing context and texlive-pictures, I tried to render this code with context:

    \usemodule[tikz]
    \usetikzlibrary[positioning,fit,calc]

    \starttext
      Lorem Ipsum
    \stoptext

With this command:

    context test.tex

I expected it to produce a PDF. Instead, I get the following error:

    resolvers > modules > 'tikz' is not found

    tex error > tex error on line 2 in file [...]/test.tex: ! Undefined control sequence

    <recently read> \usetikzlibrary

So, ConTeXt does not find the tikz module although it is installed. For good measure, I tried to install texlive-full, but the error persists. I first asked on tex.se, where a user commented that this is a bug and should be reported:
