Hello, |

With the upgrade from gdmodule-0.56 -> gdmodule-0.56-r1 the following |
| 4 |
sage test now fails |

|

sage -t -long -force_lib "devel/sage/sage/matrix/matrix2.pyx" |

The 0.56-libs.patch that's the reason for the upgrade (which appears to |
| 32 |
be the thing to do) actually prevents Sage from finding PNG support. |
| 33 |
The older version still works. |
