testing plpython3u on 9.0beta2

I received two errors (described below) in installing 9.0beta2 on Kubuntu
10.04 , RhodiumToad on IRC recommended I post them here.

I did not have a 2.x or 3.x python dev installed, but I was really only
interested in python3 via plython3u.
So...
sudo apt-get install python3-all-dev

Configure works fine...
"./configure --with-pgport=5433 --with-python --with-ossp-uuid --with-libxml
--with-libxslt --with-perl"
"make" fails while trying to build plpython, Cannot find python.h i
believe....(I sadly did not save the text of the error and have since
continued onward. But it was not finding a file while building plpython. I
believe I would have to uninstall a few things to reproduce.)
So I tried installing the 2.x dev. After running "sudo apt-get install
python-all-dev" then "make;make check;sudo make install", it all worke fine.

However, when issuing a "createlang plpython3u template1", I get
"createlang: language installation failed: ERROR: could not access file
"$libdir/plpython3": No such file or directory". But if I "createlang
plpython2u template1" first, then it will allow "createlang plpython3u
template1".

Am I doing something incorrect, or...?

(As an aside, functions created with LANGUAGE plpython3u appear to work.)
