Following Wolfgang's advice (thanks) I have followed the delicious  
thread.
So I have
1. downloaded the fonts and installed automatically via macosx  
Fontbook app (they are available in my system)
2. I have created a file named type-delicious.tex containing:

\starttypescript [sans] [delicious]
\setups[font:fallback:sans]
\definefontsynonym [Sans] [Delicious-Regular]
\definefontsynonym [SansItalic] [Delicious-Italic]
\definefontsynonym [SansBold] [Delicious-Bold]
\definefontsynonym [SansBoldItalic] [Delicious-BoldItalic]
\definefontsynonym [SansCaps] [Delicious-Caps]
\stoptypescript

\starttypescript [sans] [delicious]
\definefontsynonym [Delicious-Regular] [name:Delicious-Roman]
[features=default]
\definefontsynonym [Delicious-Italic] [name:Delicious-Italic]
[features=default]
\definefontsynonym [Delicious-Bold] [name:Delicious-Bold]
[features=default]
\definefontsynonym [Delicious-BoldItalic]
[name:Delicious-BoldItalic] [features=default]
\definefontsynonym [Delicious-Caps] [name:Delicious-SmallCaps]
[features=default]
\stoptypescript

\starttypescript [delicious]
\definetypeface [delicious] [ss] [sans] [delicious] [default]
\stoptypescript


(which I do not understand: but that's another story)

I have saved the file under the same folder of tex file I'm working at

3. then I have called: context --generate

4. In my tex file I have added:
\usetypefile [delicious]
\usetypescript[delicious]
\setupbodyfont[delicious]

5. while compiling I'm having a problem with  delicious.
Log attached

?
Thanks

Best
