  If the minimal supersymmetric standard model (MSSM) is the only new physics
around the TeV-scale, it has to account for the entire dark matter relic
density, or else it will cease to be `minimal'. We use this expectation to
obtain the best quantitative explanation of the galactic centre $\gamma$-ray
excess. The $\gamma$-ray data/flux limits from other astrophysical sources are
also taken into account, together with all laboratory constraints. The lower
limit on the relic density, together with the latest direct dark matter search
constraints and the shape of the galactic centre $\gamma$-ray spectrum, makes
the MSSM fits appear rather poor. A comparison with similar fits of the Higgs
boson mass from indirect and direct search results makes one suspicious that
the MSSM is not a good explanation of data related to dark matter.
