[NTG-context] map problems

Hi. A year ago I wrote a set of ConTeXt-set documents on gentoo linux with teTeX without any problems. Now, trying to update them on Mac OS X with Gerben Wieda's teTeX distribution, I get these messages specials : fdf,tpd loaded ) pdftex : using map file: original-context-symbol.map pdftex : using map file: pl0-ams-cmr.map pdftex : using map file: original-vogel-symbol.map ) * Seaching Google, I found some references to this problem, but all in connection with installing new fonts. Since Gentoo managed to set up everything automatically, I wonder if there is a simple fix for that. Thanks, Boris.
