If the source changes a lot, the patch command is not able any more to (re)locate the hunks. In such a case a patch needs to get rebased, as you already suggested. You can do so by manually comparing the hunks with the new source.Hi Raphael,thanks for the patch but I was aiming at having v0.93.1 into Fedora. This already compiles fine (not as v0.92).
What I miss is to port the dropsgid patch to 0.93.1 (I tried and I failed).
Please have a look at:

Sorry I can not help any further due to lack of free time ATM.If you don't think it is feasible I'll release another v0.92 with your patch to fix FTBFS.
