Hello ConTeXt-Crew, thank you very much for this fantastic application. I'm a former LaTeX-user and now I can't imagine to go back ever. Recently I tried to install ConTeXt in an android smartphone with help of the app "debian noroot". Everything went fine and I'm able to compile documents, but all \framed-Commands lead to the error-message "tex error on line 2 in file...: !You can't use '\hrule' here except with leaders" The minimal example is: \starttext \framed{Hello} \stoptext I suspect the cause for this might be missing packages (metapost?). Can you give me any hint, what packages I have to install? I installed the ConTeXt Standalone from contextgarden and I'm running context version 2016.01.18 22:21 (ConTeXt Process Management 0.63). I already tried to install the package texlive-metapost, but it didn't help. Help would highly be appreciated. Thanks in advance Thomas Klein.
