You can find out what a port installs with e.g. "port contents tcl"

Yes, the Tcl program is called tclsh.

I'm not familiar with lib_MACOSX. The instructions you're referring to say

So I think "lib_MACOSX" is a detail of how they've set up their machines at UIUC and not something you would find on your machine or other machines.

The instructions you're referring to mention Mac OS X 10.2, released 18 years ago, so the instructions may not be much use today; not only macOS but also Tcl may have changed since then.
