help needed: Updating pyqt to 4.11.1

Unfortunately this fails to compile (on Mavericks) with the following linker error: http://pastebin.com/rWmepPhu

Possibly this is related to Homebrew building with the custom libc++ makespec.

Any ideas?
Can someone point out to me how to best copy the contents of a directory to a subdirectory (without that subdirectory itself) in ideomatic ruby?
