PostScript font access problem

["Denis B. Roegel" <Denis.Roegel@loria.fr>]

I have what seems a very common font problem.
I have had this problem before, but now I really need to understand
why it doesn't work and to get it working. 

For the record, I have installed the latest ConTeXt, and am using 
the TL6 (not yet 7) with the pdftex on CTAN.

My input file is

\starttext

test 

\showbodyfont[pos]

\stoptext

I get:

-----------------------
...
(/usr/share/TeX/texmf/tex/context/base/type-exa.tex))kpathsea: Running mktextfm
+ec-utmr8a
/usr/share/TeX/texmf/web2c/mktexnam: Could not map typeface abbreviation c- for
+ec-utmr8a.

+/usr/share/TeX/texmf/fontname/special.map?
mktextfm: Running mf \mode:=ljfour; mag:=1; nonstopmode; input ec-utmr8a
This is METAFONT, Version 2.7182 (Web2C 7.3.3.1)  

kpathsea: Running mktexmf  ec-utmr8a 
! I can't find file `ec-utmr8a'.
<*> ...jfour; mag:=1; nonstopmode; input ec-utmr8a

-----------------------

>From what I see, ec-utmr8a is a synonym for utmr8t (see type-enc.tex).
Then I have both utmr8t.tfm and utmr8t.vf. Hence, ConTeXt
should have what it needs.

utmr8t.vf leads to utmr8r (from vftovpl utmr8t.vf) and I have
utmr8r.tfm as well as utmr8a.pfb to which it leads
in dvips/urw/utm.map (and also in dvips/psfonts.map).

Anyway, I think these considerations are irrelevant, since it seems
ConTeXt doesn't follow the synonyms. Or have I again forgotten
something?

Thanks,

Denis
