[NTG-context] typefile with absolute path to file

Dear List, a question about \typefile{}. I tried to use \typefile{ /with/an/absolute/path/to/some_file } and failed Message in the log: Verbatim some_file not found. Also tried with no path at all, assuming it will take the file from the current directory. Same result. Do I miss something? Should this work? Or, if not, how can I achieve this effect (typefile with absolute path to a file. btw. on a Linux system) I'm aware of a similar message thread to this list from May 25th, this year. But I didn't feel that it speaks against my comprehension of \typefile ... Thanks! Erik
