Trying to execute LibcxxOnOlderSytems (2nd ed.)

[ftp83plus]

Ok, after a night of fetching-compiling, it now fails at step 6

--->  Unable to uninstall llvm-3.4 @3.4.2_8, the following ports depend on it:
--->  	cctools @877.5_2+llvm34
--->  	ld64-136 @136_2+llvm34
Error: org.macports.uninstall for port llvm-3.4 returned: Please uninstall the ports that depend on llvm-3.4 first.

The previous step 5 succeeded, but did it kept the clang-3.4 as well as the clang-3.7 variant?
