Hans, Taco, Gerben, et al,

With the new release of Context, it looks like you have the same:

--ro=TEXMFMAIN

I've attached my type-tmf-gw.dat and the type-tmf-gw.log that  
resulted from a run with:

sudo texfont --encoding=ec type-tmf-gw.dat

I did this by dropping type-tmf-gw.dat in ~/tmp/. The first time I  
ran it with:

sudo texfont --ma --in type-tmf-gw.dat

That got the texnansi encoding. I sent that file previously.
