the 'MAKE XCONFIG' gets the message: 'Error in startup script: invalid command name "button" '. It also says line 26 of script kconfig.tk which shows "button .ref".
You probably do not have the proper support libraries installed on your system. Make sure you have tcl-8.0.3-20.i386.rpm tk-8.0.3-20.i386.rpm installed on your system. make xconfig requires those.
