[Pythonmac-SIG] Tcl/Tk path problems with py2app

[John Gleeson]

OS X 10.3.7 w/Apple's python framework
py2app 0.1.7
TclTkAquaBI-8.4.9.0.dmg


I am trying to use py2app to build a standalone Leo application from  
the latest release of leo <http://leo.sf.net>.

When I execute leo from the command line, its Tcl/Tk  gui works as  
expected, so I presume Tcl/Tk is installed correctly.  I also have a  
Leo app created by Guenther Enthaler last summer  
<http://sourceforge.net/forum/forum.php? 
thread_id=1064013&forum_id=10226>  that works fine; it is not   
standalone - the user must have Tcl/Tk installed.

But when I launch the standalone Leo.app that I create with py2app, it  
fails with

TclError: Can't find a usable init.tcl in the following directories:
     /usr/lib/tcl8.4  
/System/Library/Frameworks/Python.framework/Versions/2.3/lib/tcl8.4  
/System/Library/Frameworks/Python.framework/Versions/lib/tcl8.4  
/System/Library/Frameworks/Python.framework/Versions/2.3/library  
/System/Library/Frameworks/Python.framework/Versions/library  
/System/Library/Frameworks/Python.framework/Versions/tcl8.4.9/library  
/System/Library/Frameworks/Python.framework/tcl8.4.9/library  
/usr/lib/tcl8.4
This probably means that Tcl wasn't installed properly.

The Tcl and Tk frameworks are in the app bundle (and init.tcl is there  
too), but Tcl does not search there.  I tried wrapping the Leo  
executable in a shell script so I could set the environment variables  
TCL_LIBRARY and TK_LIBRARY to point into the frameworks inside the app.  
  That got me past the TclError above and a similar TkError.  The Leo  
user ID input dialog even worked.  But then Tk failed to draw widgets,  
again looking in the wrong places on the system.

Does anyone have any ideas why Leo.app is not using the Tcl and Tk  
frameworks that py2app cop-ies into it (or the ones installed on my  
system)?

The source I'm using can be downloaded from the following link if  
anyone would like to try it out.  It also contains logs of all of my  
"python setup.py py2app" output and the console output from Leo.app.   
The console output includes a dump of my environment variables,  
sys.path, etc. (pirated from the Hello.py py2app example).
