I don't know how it happened, but recent Ubuntu builds have broken -dev packages, which contain same libraries as non-dev packages.

I don't know where to file a bug or who's maintainer, but it would be great to fix that.
That would be my fault and the component in the bugzilla is Packaging/apt.
I am going to have a look to this. Sorry, I added recently some missing
files in the packages.
It should be fixed. Can you confirm?

Nope. Sorry. Still doesn't work here:

I fixed it later. It should be ok now
I am sorry, now there is an error with libclang vs libclang-dev:

It seems that latest libllvm3.5 packages are built with too recent libstdc++ version which makes impossible to install any of llvm Ubuntu builds on <13.10
The following packages have unmet dependencies:
libllvm3.5 : Depends: libstdc++6 (>= 4.8) but 4.7.2-2ubuntu1 is to be installed
Can you please have a look? We still have guys have that haven't upgrade to latest LTS.
Clang requires GCC and libstdc++ 4.7+ now that we’ve switched to C++11:
We have instructions there for building a modern version of gcc. It’s really easy to build it these days. Install into something local like $HOME/gcc/install and then pass appropriate -L and -Wl,-rpath flags to the LLVM build. I do this on 12.04 and it works fine.

Maybe I wasn't clear enough, but I just report that official http://llvm.org/apt/ Debian/Ubuntu 3.5 packages are broken for <13.10.
Do you confirm that you have also the backport installed?

I think we can narrow it down to the 12.10 which is used by one of the professors here @ my univ. There are no 12.10 gcc-4.8 builds unfortunately, take a look:
Guess this has to be noted somewhere, or maybe Ubuntu builds should stick to only supported Ubuntu versions, which makes 12.04, 13.10 & 14.04 I believe. Anyway we gonna upgrade all our workstations to 14.04 soon.
