As we pointed out in previous discussions, you just need to install
files in a version-mangled directory. Nothing hard. Just work.

Yes, you install the symbols, good. But ns-3 debug builds are built
with -O0. I want -O0 builds and -O3 builds and maybe -O3 builds as
static libraries. You need to mangle these options in the binary
filenames.

related to 1) and 2)

Let me rephrase: I would like to make sure that the issues I
mentionned are fixed _before_ the package gets in a fedora repo,
whatever release date you target.
