I think you must be able to find the old version somewhere, but I don’t have a clue how... :(

Well, in order to make use of the MacPorts-installed clang you will have to check which compiler
is currently configured as to be used (you must have the port “clang_select” installed):
---
$ port select --list clang
Available versions for clang:
	mp-clang-3.3
	mp-clang-3.4
	none (active)
---
Here you see that none is used, which will be the same for you, I guess.

So, in order to set another compiler as your system compiler switch to it by using
---
$ sudo port select --set mp-clang-3.4
---

Same holds if you want to select a specific gcc:
---
$ port select --list gcc
Available versions for gcc:
	apple-gcc42
	mp-gcc48
	mp-llvm-gcc42
	none (active)
---

I hope this helps.

Greets,
Marko
