Hi Ryan,

It’s always a good idea to send questions to the mailing list (that gives other 
people a chance to answer this - probably better than me).

First, I would take a look at what kinds of change have been made to configure 
- it’s not impossible for things to get out of sync.  If it’s just script line 
numbers, for example, you can probably carry on with your changes.

I tend to use “autoreconf -fv” (but the basic principle is much the same)

If you have the choice (I have no idea whether 
2d280e7eafc086e9df85f50ed1a6526d6a3a204d is a commit that corresponds to a 
release) - perhaps pick a commit that corresponds to a released version of the 
branch (at least as a starting point).

HTH & g/l
