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.
