Comment:
As for `gpredict`: the current [`configure.ac`-git-version](https://github.com/csete/gpredict/blob/master/configure.ac#L52) (lines 52 and 109) checks for goocanvas 2 or 3 and both versions seem to be interchangably.

Just tested it – this time really with goocanvas-3.0 ;) – and it works.

However, a simple `sed` sufficies:
```
pre_configure() {
        vsed -i "s/goocanvas-2.0/goocanvas-3.0/" configure
}
```
