Bug#696913: llvm-3.2-dev: consider saving disk space by not shipping two identical copies of libLLVM-3.2.so.1

[Timo Juhani Lindfors]

Package: llvm-3.2-dev
Version: 3.2-2
Severity: wishlist

I noticed that my system has two copies of the same 21 MB shared library:

$ stat /usr/lib/x86_64-linux-gnu/libLLVM-3.2.so.1 /usr/lib/llvm-3.2/lib/libLLVM-3.2.so.1

$ md5sum /usr/lib/x86_64-linux-gnu/libLLVM-3.2.so.1 /usr/lib/llvm-3.2/lib/libLLVM-3.2.so.1

$ dpkg -S /usr/lib/x86_64-linux-gnu/libLLVM-3.2.so.1 /usr/lib/llvm-3.2/lib/libLLVM-3.2.so.1
libllvm3.2:amd64: /usr/lib/x86_64-linux-gnu/libLLVM-3.2.so.1
llvm-3.2-dev: /usr/lib/llvm-3.2/lib/libLLVM-3.2.so.1

Is this a bug? Would it be possible to save disk space by only
shipping one copy?
