Astronomy Symbols in ConteXt

Question

I sticked to the explanation here: http://wiki.contextgarden.net/Symbols but the minimal example

\usesymbols[was]
\setupsymbolset[wasy astronomy]
\starttext
\symbol[mercury]
\stoptext

Only shows the word "mercury". What am I missing?

Edit: Also not working with:

\usesymbols[mvs]
\setupsymbolset[astronomic]
\starttext
\symbol[Mercury]
\stoptext

I get the error:

fonts           > defining > forced type 'ttf' of 'marvosym' not found
fonts           > defining > font with asked name 'marvosym' is not found using lookup 'file'
fonts           > defining > unknown font 'marvosym', loading aborted

But ttf-marvosym is installed, texlive-fonts-recommened is installed and all folder are exported to OSFONTDIR

Answer 1

It works just fine here with TL 2016

mtx-context     | ConTeXt Process Management 0.63
mtx-context     |
mtx-context     | main context file: /usr/local/texlive/2016/texmf-dist/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2016.05.17 19:20

The example

\usesymbols[mvs]
\setupsymbolset[astronomic]
\starttext
\symbol[Mercury]
\stoptext

produces

Please check whether you installed ConTeXt correctly.
