This looks incorrect.  Why does the Frameworks/ directory contain
a Frameworks symlink?  That means one would need a search path like

 /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks/Frameworks

to find them.  Did something modify this SDK since it was installed?

I think we need "-Wl,-v" to get the linker to tell us what framework
search path it is using.  Try with and without the -isysroot option.
