Sorry forgot to send the modified texconfig.
In any case a better solution to the "ed" missing
problem is to include in /usr/bin the following
shell script, with the name "ed" :

	#!/bin/sh
	vim -e $1 $2 $3 $4 $5 $6
	exit

Don't forget to make it executable
	chmod +wx ed

Good luck

Please make sure, their values are ok, and otherwise change or unset them.
If you continue with wrong values for the above variables, $progname
might run into trouble when locating files on the disk.

Note that you can refer to the default path by giving an "empty" path
component (i.e. a colon in front or in the end, or a doubled colon
somewhere in the middle).

If you set TEXINPUTS, e.g. to :~/TeX/macros, (La)TeX will search along
the default path and then in ~/TeX/macros.

For more information, see the Kpathsea and the teTeX manual.
