Sorry, I can't help, because I don't have Windows available. And the following won't show any traces of tcl include files or libraries on my Linux box: 
cd Tk-TableMatrix-1.01
strace -f -eopen perl Makefile.PL | & grep -i tcl
strace -f -eopen make | & grep -i tcl
strace -f -eopen make test | & grep -i tcl

I can't think of any reason why this should be different on Windows.

Update: -f added
