I would have been glad to ignore that myself, but that was before I had to
deal with this CBC spkg.
Here's the problem : during the "./configure" step CBC detects (on linux)
that the rt library is available and detects (on mac) that it is not in
which case it uses a different code. The libraries are built. Then we
build the coin_backend.pyx file in Sage, which calls the Coin library,
hence this file has to be linked with the coin library. If (under linux)
we do not also link coin_backend.pyx with rt then we get an exception
saying that a function is missing in the lib. So we have to add a "rt"
flag to module_list.py so that Sage links it. Yeah, but then it does not
compile on Mac anymore because the library does not exist.
Ideally, we would like to force the ./configure script to ignore the rt
library on linux but I have no idea how to do that.
Would you know how to get away with all that ? `:-P`
