This is the same type of bug that ​#23204

Symbol visibility control disabled.

Attached a patch to fix this issue (patch-config.tests-unix-fvisibility.test.diff)

Is this issue still relevant as of r72571 with qt4-mac being at 4.7.0?

Fixed in r73102. ccache works nicely for me!

Had the same issue today, on linux. The patch here fixed it, so I submitted for inclusion in Qt 5 (​http://codereview.qt-project.org/11133 - you might need an account to see it).

Are you saying that this ticket's issue is still valid, for MacPorts on OSX? Or, that it's still an issue under Linux?

I cannot see your patch. Can you attach it to this ticket?
