Strange problems with teTeX 3.0

hello - I am trying to install 3.0 on a cluster of about 15 pc 
i686-pc-linux-gnu.  I have installed in /usr/soft/teTeX-new/, saving the 
old tree in /usr/soft/teTeX/ as suggested.  the building of the 
executables went ok.  what I have troubles with is:

I have custom fonts, and I want them known to LaTeX.  I have, as root, 
changed TETEXDIR=/usr/soft/teTeX-new and changed PATH etc... in the 
following way:

       PATH="`echo $PATH     | sed -e 's/teTeX/teTeX-new/'`"
    MANPATH="`echo $MANPATH  | sed -e 's/teTeX/teTeX-new/'`"
   INFOPATH="`echo $INFOPATH | sed -e 's/teTeX/teTeX-new/'`"

I have updated $TETEXDIR/share/texmf-dist/web2c/updmap.cfg in the 
following way:

- uncommented "Map lucidabr.map" and "Map lumath.map";
- uncomment "Map mt-yy.map" and "Map mt-plus.map";
- commented "#! Map mt-belleek.map";
- added to the end the following lines:

# Additions MLO 08-Mar-2005
# CM-super fonts
MixedMap cm-super-t1.map

# Adobe Euro fonts
Map zpeu.map

# Micropress Baskerville
Map baskerville.map

# Micropress Informal Math
Map iffonts.map

# BrushscriptX-Italic
Map pbsi.map

# Optional Adobe fonts
Map optadobe.map

and then run "updmap".  LaTeX does not recognize my fonts, and, with my 
GREAT SURPRISE, 
$TETEXDIR/share/texmf-var/fonts/map/dvips/updmap/psfonts_t1.map is 
UNCHANGED.

I have then manually edited psfonts_t1.map (I know, it's forbidden), 
inserting all the font declarations at the end for lucida/mathtime/all my
other fonts; LaTeX chokes again because cannot find cm.enc, needed by the 
cm-super fonts; but cm.enc is there, in the texmf-local tree, in 
$TETEXDIR/share/texmf-local/fonts/map/dvips/.  kpsewhich cm.enc types 
*nothing*.  running texhash does not change anything.  I don't understand 
what's happening --- could you help please?  please?
