Problem following "OpenType installation basics for ConTeXt" article

[Gavin Sinclair <gsinclair@gmail.com>]

Greetings (first post),

Adam Lindsay's recent article "OpenType installation basics for
ConTeXt" in The PracTeX Journal
(http://www.tug.org/pracjourn/2005-2/lindsay) is very well written.
Unfortunately, I was unable to perform the first step.

As the article specified, I ran the command:

$ texfont --ma --in --ve=public --co=torunska --lcdf --pre --va=liga,kern

It started off OK, but failed to properly create the map file.
Selected output follows:

   extending map file :
E:/MiKTeX/local/fonts/map/pdftex/context/texnansi-LIGA-KERN-public-torunska.map

      font identifier : AntykwaTorunska-Bold -> text -> tfm
     processing files : otf -> tfm + enc
otftotfm: './AntykwaTorunska-Bold.otf': No such file or directory
no mapfile from otftotfm : texfont.map

      font identifier : AntykwaTorunska-BoldItalic -> text -> tfm
     processing files : otf -> tfm + enc
otftotfm: './AntykwaTorunska-BoldItalic.otf': No such file or directory
no mapfile from otftotfm : texfont.map

      [and so on for each .otf file]


So, otftotfm is claiming that the files don't exist, but they
absolutely 100% do.  Perhaps it's looking for them somewhere else?

Does anyone have any suggestions?

Regards,
Gavin
