QT4 tool options panel does not provide symbian target specific options on Mac

Working with Qt Creator on mac w/ symbian toolchain. In the mkspec directory, I create a symbolic link to the target I want to be default, e.g. ln s default symbian/linux-gcce. In creator, when I look at the QT toolchain, it says the spec is "default". However, when I do the same thing on linux- the QT4 panel will provide additional options specific to the target. For example, for default alias to symbian/linux-gcce, when I open the QT4 panel, there are additional options such as S60 SDK, CSL/GCCE directory, Carbide directory and SBS v2 directory (disabled). I don't see these options on the mac. Instead, I have to set these environment variables and export them externally in order for them to be used.

Attached to images to show the difference between ubuntu and mac with similar set-up (mkspec/default symbolic link to symbian mkspec)
