Yes that's the _source_ for the tk extensions
Ruby needs that to be compiled

good

It looks like the build process wasn't able to find Tcl/Tk headers, so
your compiled Ruby ended up without compiled tk extensions.

Can you check whether you have Tk installed in your system, and in
case the answer is positive, verify it provides the necessary header
files.

If the package you use for Tk provides the headers, it may be storing
them in a find the build process is not able to find without
assistance, so you would have to let the ruby build process know that.

Hope that helps

best,
