On some Bourne shells, you can't redirect the input of "read" that way.
I used 4.3BSD five years ago or so and I'm pretty sure that was the case.

You should probably be using command substitution instead of a "read"
command, anyway.  This command will do the same thing without a temp file:

	dir="`pwd`"
