That was annoying. The packages were rather persistent and I had to do  
all this to clean them out and relink... thanks!

sudo apt-get autoremove
sudo apt-get remove --purge postgresql-client
sudo apt-get remove --purge postgresql-client-8.4
sudo apt-get remove --purge postgresql-client-common
apt-get clean

still didn't work.
jcz at dell390:/usr/local/src/postgis-1.5.2$ ls -l /usr/bin/pg*
-rwxr-xr-x 1 root root 26260 2011-02-02 03:56 /usr/bin/pg
-rwxr-xr-x 1 root root 25912 2011-04-20 10:27 /usr/bin/pg_config
-rwxr-xr-x 1 root root 13860 2010-07-06 20:21 /usr/bin/pgrep

jcz at dell390:/usr/local/src/postgis-1.5.2$ sudo rm /usr/bin/pg_config

then
sudo ln -s /usr/local/pgsql/bin/pg_config /usr/bin/pg_config
sudo apt-get install libxml2-dev

and finally got
PostGIS is now configured for i686-pc-linux-gnu
