Comment:

 I've had the same error too, and can confirm that disabling ccache works
 around the problem. You should commit a change to the qt4-mac Portfile
 (and the qt4-mac-devel Portfile, if it's also affected) to disable ccache.
 If you can later find a better way to fix it that allows ccache to still
 be used, then by all means do that. But for now, ''something'' should be
 done so users don't run into this problem, and waste hours on failed
 builds in the process. I recommend committing the patch I'll attach
 momentarily.
