I am trying to get the combination of ConTeXt and LilyPond working.

I copied the example that I found on http://wiki.contextgarden.net/LilyPond , changing the setups a little (I don't have the font  Adobe Jenson Pro).

Processing it with mkiv from april this year and earlier produces a pdf with both zapf texts and in between the text: [[output file missing.

The log-file says: 

---------------------

t-filter  . cached output file 'lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf' missing. Rerunning filter

sh: lilypond: command not found 

t-filter  > file 'lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf' cannot be found

---------------------

Indeed there is no file lilytemp/LilyPond-ConTeXt-example-27-06-16-templilypond-0.pdf .

With LilyPond.app itself, using TeXShop as the editor, I have no problems. (But I have never been able to get it working from Terminal, generating only messages like "cannot execute binary file" and "Permission denied" even after running sudo chmod u+x .)

What can I do about it?

Thanks in advance for tips and suggestions.

Best regards,
