Issue #5048 has been updated by Wataru Kimura.

File patch-ext-tk-mac_lion.diff added

It looks the header file "tk.h" is missing in your system. 
Header files for Tk|Tcl.framework on Lion are provided by installation of Xcode 4.1 from Apple AppStore.

If the header files are not installed into target system, installation of tk modules should be skipped.
