ON A MAC: Os 10.9.2 requires Qt 5.2 but debugger does not work

[ceraolo]

I used to work with Qt 5.1, and was happy.
A few days ago I upgraded the OS of my mac into 10.9.2.
Then, when I launched Qt, it said it was incompatible with this new mac version
I upgraded to Qt 5.2 for Mac.

I use Qt creator. It compiles and run my programs, but if I click on the "start debugging" button, a severe error message box is displayed, saying:
Debugger 'usr/bin/gdb' not found.

I really don't know where to start from to solve this.
Can anyone help?

Thanks.

I've solved this.
It looks like Maverick does not come with GDB. It includes lldv, instead. I changed my kit so that it used as debugger LLDB, and now everything works well.
