[NTG-context] metafun

I have made texexec --make metafun to generate metafun format. And it said it generated it. But... I always get these messages kpathsea: Running mktexfmt metafun.mem fmtutil: no info for format `metafun'. when doing texexec --pdf to my tex-beauties... it seems that he goes for metapost after that... is there anything wrong here? thanks ! jose
