To set INSTALL_PATH you're supposed to use the option 
xcode.destroot.path. But it does look like xcode.destroot.settings is 
being used as a string without flattening it first (options are actually 
lists). That is probably easy enough to fix, but work may be required to 
adapt any ports that are assuming the current behaviour.
