Hi everyone,

I'm currently running Snow Leopard and using to compile my application that
uses libtiff. I'm bundling MacPorts libtiff in the *.app. Everytime anyone
runs my app on a Leopard system it crashes with the error above. I'm
compiling my app with -mmacosx-version-min=10.5 -isysroot
/Developer/SDKs/MacOSX10.6.sdk so it should support Mac OS 10.5. The error
only happens when MacPorts' libtiff is loaded.

Is there a way to provide libs that work with Mac OS 10.5 or is there a way
for me to get them in my 10.6?
