I admit if I would have had a quick clue I would have provided it
immediately.  Despite I'm using pbuilder basically all the time I never
experienced this problem ... most probably since I never added any *-dbg
package to the Build-Dependencies which is IMHO totally void.  Do you
have any reason for this?

So I would recommend:

$ git diff
diff --git a/debian/control b/debian/control

 Vcs-Browser: http://anonscm.debian.org/gitweb/?p=debian-science/packages/pyfftw.git

in any case.

When speaking about Build-Depends:  Please also remove quilt from
Build-Depends *and* from debian/rules (--with ...,quilt).  This is
redundant when using debian/source/format 3.0 (quilt).

After applying the patch above the package does not yet build since it
runs into:


'build/scripts-2.7' does not exist -- can't clean it
        pybuild --clean -i python{version} -p 3.3 --dir .
I: pybuild base:170: python3.3 setup.py clean 
Traceback (most recent call last):
  File "setup.py", line 25, in <module>
    import numpy
ImportError: No module named 'numpy'
E: pybuild pybuild:256: clean: plugin distutils failed with: exit code=1: python3.3 setup.py clean 


if on the building machine the packages python-numpy *and* python3-numpy
are missing.  I have no idea how autobuild machines are dealing with
this but I'd recommend asking for advise at the
debian-python at lists.debian.org mailing list how to sensibly tweak your
clean target to only clean "if necessary" and prevent setup.py from
doing useless things.

Kind regards

        Andreas.
