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
endif

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
        $reduce/redfront/redfront
else $reduce/lisp/psl/$MACHINE/psl/bpsl -td 16000000 \
      -f $reduce/lisp/psl/$MACHINE/red/reduce.img
endif

----- end -----

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

Andreas
