In later versions of tetex, texexec is a script which calls
the real texexec.pl:

=====================================
#!/bin/sh

# find out which program is wanted by
# removing everything from the first parameter
# up to and including the last forward slash.
# there are symlinks to texexec, so this script may also be
# called as texutil

what=`echo $0 | sed 's@.*/@@'`

# find the exact location of $what.pl

p=`kpsewhich -progname=context -format='other text files' $what.pl`
{ test -n "$p" && test -f "$p"; } \
  || { echo "\`$what.pl' not found."; exit 1; }

# run the script

perl "$p" "$@"
====================================

So if your teTeX is recent enough then you can leave the perl scripts
where they are. This may have nothing to do with your problem, but it
does simplify installation.
