Pb with the ./configure script

[D'Artagnan <cremasch(at)essi(dot)fr>]

Hello everybody,
i am a new member of this mailing-list, because i tried yesterday to 
install pgadmin3 on a computer i am not root on, so.... let's go to 
compile from sources !
(I am a student in charge of the installation of different GNU/Linux 
software in a french engineer school in computer sciences.)

I have installed without any problem wxWindows, and the stc "add-on" 
which is required by pgadmin3.
But i have got a problem with the "--with-wx" option of pgadmin3 : there 
is a good detection of the binary "wx-config" but the script can't find 
the stc add-on.
In the configure script of pgadmin3, i've read that, with the 
"--with-wx" option, it searches the directory "include" on the same 
hierarchical level that the directory "bin", which is totally unusual.

My structure is like this (for wxWindows) :
.
`-- 20031010-7__1
   |-- install
   |   |-- arch
   |   |   `-- Tettnang
   |   |       |-- bin
   |   |       `-- lib
   |   |           `-- wx
   |   |               `-- include
   |   |                   `-- gtk2ud-2.5
   |   |                       `-- wx
   |   `-- noarch
   |       |-- include
   |       |   `-- wx
   |       |       |-- generic
   |       |       |-- gtk
   |       |       |-- html
   |       |       |-- protocol
   |       |       |-- stc
   |       |       |-- unix   
   |       |       |-- xml
   |       |       `-- xrc
   |       `-- share
   |           |-- ...            //lots of things here about locale
   |           |-- aclocal
   |           |-- locale
   |           `-- wx
   |               `-- 2.5
   |                   |-- afm
   |                   `-- gs_afm
   `-- log

So you can see the marked difference between the architectural dependant 
files, and the non-architectural dependant files (a classical usage of 
the "--prefix" and "--exec-prefix" options)
After editing the configure script, i can start the compilation phase 
but there are some C++ errors of compilation (static cast error for 
example), so i suppose it can't find some files .h from the stc add-on.

Is there any solution for me to make pgadmin3 undertand that my 
"include" directory of wxWindows is NOT at the same place that the "bin" 
directory ?
Thanks in advance for your help.
