I have tried to repeat the example in the file "Creating metapost examples"

Can anyone give me a hint?

The two files given above are one of your source files
and an auxiliary file I need to read to find out what your
btex..etex blocks mean. If you don't know why I had trouble,
try running it manually through MPto -tex, TeX, and DVItoMP.

you have a name clash with a system file (somewhere else in your tex path); this can be solved by making sure that in case of context, tex searches on the local path first (can be done in texmf.cnf); i'm a bit puzzled, because context should make a fake file on the current path). Another option is to protect your temp job files with (in cont-sys.tex):

\protectbufferstrue

or more obscure, you can change the name of the temp files,

\def\MPgraphicfile{\bufferprefix mp\ifMPrun run\else graph\fi}

say mp -> mps , but first try the buffers
