Another question about the 'buildroot override'.
I have created a new buildroot-override from MUMPS-5.1.1.
Inside it i rebuilt a new version of coin-or-Ipopt:
Other packages (coin-or-OS, coin-or-Couenne, coin-or-Bonmin) depend by coin-or-Ipopt, but
looks i can't rebuild them for a broken Ipopt-->MUMPS dependency.
This is a coin-or-Bonmin rebuild inside the same buildroot-override from MUMPS-5.1.1:
What do i miss?
