Uninstall procedure for pgadmin3 under Mac OS X 10.3

Dear pgadmin support community members,

I need your help for some tricky problem that I was unable to solve.

I am using pgadmin under Mac OS X Panther (10.3.9).
The newest pgadmin releases only support Tiger (10.4) since they are
compiled with dynamic links against 10.4 libraries and frameworks.
Some weeks ago, one of you kindely helped me (I think it was Dave, but
sorry, I am not sure anymore) in making a special 1.6.0 build for me.

Few days ago I decided to try 1.6.2 but I forgot that it does not work
with 10.3.
I installed it, and it crashes.

No problem, I thought, I just have to delete the pgadmin "binary" (in
fact a bundle under OS X "Applications" folder), and then install back
1.6.0 "Panther" build.
No way, the installation fails when I want to choose my apps disk in
"Choose target" screen. The error is a bit cryptic for me, the message
is (in fact it is in french, my translation could be errored) "You
cannot install this software on this volume. (null)".
I tried to delete preferences files or "Application support" files I
found in my "user"/Library, but it still failing...

What is the procedure to uninstall it ?
I looked after help or docs on the internet, but it was unsuccessfull.

Thanks for your help,
Yannick.

PS : You could told me that I'd better compile my own pgadmin build. I
will, but just for now I am too busy to spend time in compiling
wxwidgets and so on.
