I've successfully built DOLFIN using the steps you describe above.

I'm now also packaged an *extremely* primitive Debian package for PETSc 
2.2.1. This uses the steps you describe above, with the difference that I 
use PETSc's 'make install' target.

I've not used Powell's packaging. I tried, but had difficulty 
understanding it, so opted for a from-scratch approach.

To build dolfin against this build of petsc, I ran

./configure --with-petsc-dir=/usr/lib/petsc-2.2.1

I got the error messages

make: *** No rule to make target `getincludedirs'.  Stop.
make: *** No rule to make target `getlinklibs'.  Stop.

However, the configure script does not actually stop. :-)

But, later on it cannot find the include dirs etc. In successful builds 
these messages did not appear. On further investigation, I see it is 
trying to source files inside the directory 'bmake', possibly 'variable'.

Please take a look and let me know what I am doing wrong. At a superfical 
comparison, the result looks similar to an in-place build like you 
suggested. I do think that DOLFIN should be able to build against the 
unmodified result of a 'make install'.

You can get my version of petsc 2.2.1 from

deb http://www.cbcb.duke.edu/~faheem/debian/ ./
deb-src http://www.cbcb.duke.edu/~faheem/debian/ ./

Just do

apt-get source petsc

or

apt-get install libpetsc

As I said, this is extremely primitive, so any comments for improvement 
would be appreciated.

Note that one thing that should be improved, is that according to apt, the 
space used by this package is 130 Mb, while Powell's package for 2.2.0 was 
around 11 Mb. So there is room for trimming down and breaking into smaller 
packages.
