OK. configure does not exist in this case.

Interesting. In my case the ptxversion does not work because intltoolize
needs to be run as well. But it is good to know this.

For packages where the ptxdist version works, shall I just copy the generic
autogen.sh over to patches/<package>-<version>

Bonus question. If there are no other patches, ptxdist complains in the
extract stage saying that the series file was not found (although this does
not prevent it from continuing to the extract.post stage). Is this ok?

4. If you need to use the package specific autogen.sh, the

OK, this is good to know as well. This way I don't need to mess with stage
rules.
