Of course you are right. But I know no way to disable redfront using

To my knowledge, if Reduce is properly installed, then the reduce environment variable should be set in your profile, and the other variables should be set in your reduce startup script. This is the startup script for 3.8 that I have on a solaris machine:

----- start -----
#!/bin/csh -f
# Script to load PSL REDUCE. It should be installed in /usr/local/bin,
# somewhere in your search path.

if ("`env | grep '^reduce'`" == "" ) then
setenv reduce /private/packages/scientific/reduce3.8

setenv MACHINE solaris
setenv lisp psl
setenv gnuplot $reduce/wutil/$MACHINE
setenv GNUPLOT_DRIVER_DIR $reduce/wutil/$MACHINE

if ( (-e $reduce/redfront/redfront) && (`$reduce/util/isatty` != "0") ) then
else $reduce/lisp/psl/$MACHINE/psl/bpsl -td 16000000 \
      -f $reduce/lisp/psl/$MACHINE/red/reduce.img

----- end -----

Redfront should be disabled here in the if expression, if $TEXMACS_REDUCE_PATH is set.
