configure: error: Installation of tcl seems incomplete or can't be found automatically.
Please correct the problem by telling configure where tcl is
using the argument --with-tcl=/path/to/package
(perhaps after installing it),
or the package is not required, disable it with --with-tcl=no.

Makefile.in is newer than Makefile.
You need to re-run configure.

These lines seem to be the problem:

It seems that tcl is not installed, or the compiler cannot find it. I would first check to see that it is installed. Check the repositories of your distribution and search for tcl. A few packages should come up. Installing tcl and tcl-dev (or similar, depending on distribution) should at least get you to the next step hopefully. Make sure those packages are installed and try again.

If you're absolutely sure those packages are installed, using the tag (according to the above error) should tell the configure script where the necessary libraries are located on your system.

Good luck!

in general do not use root to build software (use normal user to execute configure). In your case you will need to install tcl first and clean up your environment before switching to another user.
