I can't tell you, but apparently you haven't done exactly what you  
said here. Have you used otool on the actual build product of the  
framework? If you really set the INSTALL_PATH to what you said that's  
what otool -L should give. You may have copied an old version of the  
framework into your app bundle? The way we are making sure build  
products like frameworks are found is to use a shared build products  
directory for all the projects. That's much easier and more reliable  
than hard coding the (relative) path to the build framework from your  
app.
