tcl/tk version problems after upgrade to 8.5.10

[Marshall Perrin]

Hi, 

After running a recent port selfupdate/port upgrade outdated, I'm having trouble getting back to a functional tcl/tk for use with Python's Tkinter. 

Immediately after the upgrade, I encountered the "tcl not built with coreFoundation" bug. I fixed this by applying the patch from http://trac.macports.org/ticket/21968 . (Out of curiosity, why has this patch not been incorporated into the tcl Portfile, at the very least as a variant? It's a pain to have to patch this after every minor version number bump.)  That installed fine, and I no longer get that error message.

However, now I'm getting a new one: 

_tkinter.TclError: Can't find a usable tk.tcl in the following directories:
>    /opt/local/lib/tcl8.5/tk8.5 /opt/local/lib/tcl8.5/tk8.5/Resources/Scripts /opt/local/lib/tk8.5 /opt/local/lib/tk8.5/Resources/Scripts /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/lib/tk8.5 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/lib/tk8.5/Resources/Scripts /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/lib/tk8.5 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/library

This is quite odd, because I do have Tk 8.5.10: 

mperrin at prometheus ~ > port installed tk
>The following ports are currently installed:
>  tk @8.5.10_0+quartz (active)
>mperrin at prometheus ~ > port installed tcl
>The following ports are currently installed:
>  tcl @8.5.10_1+threads (active)


I'm guessing this may be due to some kind of path problem, but I can't imagine what, since this was working perfectly fine on this machine recently using tcl & tk versions 8.5.9. Any suggestions?  Thanks much.
