[PyQt] qtdirs.app can't load QtCore

I'm trying to build PyQt 4.5.1 from source on Mac OSX 10.5 x86 and I'm 
running into a problem right from the start in that the qtdirs.app built 
during the configure step won't run because it won't load QtCore.   I've 
done an otool -L on "qtdirs.app/Contents/MacOS/qtdirs" and it doesn't 
have any path prefix in front of the reference to QtCore. 

Note that my Qt install is *not* a standard install.  It is a custom 
build installed into 
"/Users/dpeterson/py/qtbuild/install/Qt-4.5.1-1.egg/EGG-INFO/usr".   I 
have verified I can run all the Qt apps, tools, and demos from this 
install.   I have exported QTDIR set to this path prior to invoking 
PyQt's configure.py script.  It looks like the build of the qtdirs.app 
is picking up all the right paths for this install.  But it looks to me 
like PyQt's qtdirs.app assumes that the various Qt frameworks are in the 
system location, even though configure explicitly passed the right 
location for my frameworks via a -F flag to g++.   Is this a bug with 
PyQt's qtdirs build process?

Here's some output:

Thanks in advance for any help!
