scid

I tryed to compile scid (./configure) on my system and was not successful.
The output is as follows:

configure: Makefile configuration program for Scid
Renaming "Makefile" to "Makefile.bak"
Tcl/Tk version: 8.4
Your operating system is: Linux 2.6.11-1.1369_FC4
Location of "tcl.h": not found
Location of "tk.h": not found
Location of Tcl 8.4 library: /usr/lib
Location of Tk 8.4 library: /usr/lib
Location of X11 library: /usr/X11R6/lib
Checking if your system already has zlib installed: yes.
Not all settings could be determined!
The default Makefile was written.
You will need to edit it before you can compile Scid.

It seems to be looking for tcl.h & tk.h files. Is there an rpm that will
install those two files and where would I get it for a fc4 system?
