If it's just the Tcl installer, that makes more sense. I'd guess it's
an sudo/environment issue, wherein su or sudo -s don't have TMPDIR.

$ sudo su -l
root# echo $TMPDIR

root# env
TERM=xterm-256color
SHELL=/bin/sh
USER=root
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/Library/TeX/texbin:/opt/X11/bin
PWD=/var/root
SHLVL=1
HOME=/var/root
_=/usr/bin/env

If that guess is correct, you could try 
sudo -s
export TMPDIR=/tmp
./install-blah-blah
