I'm using pbuilder.

I agree that I was using UNRELEASED in my attempt yesterday.  If I try
jessie-backports as target distribution I get:

...
cd sage && python ../debian/pruner/pruner.py || false
libfplll will not come from debian!
159 system packages will be used
...

I have no idea why the patches should not be applied when using
pbuilder.

I've attached both gziped logs (hope these will make it through list
filters).  In any case anybody should be able to reproduce the problem
once the latest Build-Depends are accepted Jessie backports.

Kind regards
