You are mixing up two very different things.
#1 is building and installing gnuplot from source files.
#2 is downloading and installing whatever gnuplot
package your distribution provides.

Pick one or the other.

Good so far.  Assuming that you were happy with the 
output it shows about what optional components are
being built, you should now have a runnable gnuplot
sitting in the directory where you built it.

But now you go completely wrong.
"apt install" ignores the thing you just built.
It goes out and looks for a package named "gnuplot" on
some Ubuntu web site somewhere.  Then installs it.
Not the one you built.

That is checking the copy you built at step 1.

That is trying to insall the copy you just checked,
but it will probably fail because you don't have the
right permissions.  Probably you need

                sudo make install

Now you are back in camp #2. It is reporting on installation
of the Ubuntu package rather than the newer gnuplot you just built.
Don't do this.   Do _not_ run "apt".

	hope that helps,
