Comment:
Sorry again, got a little confused with old and modified packages on my system, but all sorted out now. ;)
`gscan2pdf` does work as mentioned above without problem (I was actually still using the unmodified `perl-GooCanvas2`).

So, to summarize, with the two `sed`s applied to `gpredict` and `perl-GooCanvas2`: `gscan2pdf` and `gpredict` work fine here. :)
