Building problem of GIMP 1.2.4 under Windows.

Hi,
    First,I need to thank Tor Lillqvist. With his website, I can have
a chance to have a freeware for image editing program and its updated
source code. Secondly, I need to appreciate Kevin Myers's messages
"Building the GIMP".  I am a newbie of writing the program in MinGW.
With this messages, I have a hints to start to re-build GIMP. 
However, I got problems while running "./configure.kam".
  
****************************************************
1. Run confiure.kam, It said that it can't find pkg-config. the
message is shown below.
./configure: /c/gimpsdk/source/gimp-1.2.4/po/POTFILES.in: No such file
or directory
mkdir: cannot create directory `intl': File exists
touch: creating `plug-ins/perl/po/Makefile.in.in': No such file or
directory
checking for pkg-config... no
*** The pkg-config script could not be found. Make sure it is
*** in your path, or set the PKG_CONFIG environment variable
*** to the full path to pkg-config.
*** Or see http://www.freedesktop.org/software/pkgconfig to get
pkg-config.
configure: error: Library requirements (gtk+-1.3-win32-production >=
1.3.0) not met; consider adjusting the PKG_CONFIG_PATH environment
variable if your libraries are in a nonstandard prefix so pkg-config
can find them.

ACTION: I put pkg-config.exe with its related files
(libglib-2.0-0.dll, libintl-1.dll and iconv.dll) in the same directory
and run it.


************************************************************
2. Run configure.kam, where pkg-config and the related files are in
the same directory. In this time, it can't find the library of jpeg,
tiff and png libraries, although I have those libraries and write the
include and library path in "configure.kam". Error message is shown
below
checking for XmuUpdateMapHints in -lXmu... no
configure: WARNING: *** webbrowser plug-in and gimp-remote will not be
built (XMU library not found) ***
checking for aa_printf in -laa... no
configure: WARNING: *** AA plug-in will not be built (AA library not
found) ***
checking for jpeg_destroy_decompress in -ljpeg... no
configure: WARNING: *** JPEG plug-in will not be built (JPEG library
not found) ***
configure: WARNING: *** XJT plug-in will not be built (JPEG library
not found) ***
configure: error:
*** Checks for JPEG library failed. You can build without it by
passing
*** --without-libjpeg to configure but you won't be able to use JPEGs
then.

ACTION: I simply by-pass those libraries first.


****************************************************
3. Run configure.kam without jpeg, tiff and png library, it said that
I miss the config.pl file.  I check it in all of the folder. It is not
in there.  The error message is shown below.
config.status: creating plug-ins/makefile.mingw
config.status: creating plug-ins/perl/config.pl
config.status: error: cannot find input file: plug
-ins/perl/config.pl.in

Is there somethings wrong that I made? I really don't know what I
should do. Does any expert can give me some advices? 


******************************************************  
P.S.
By the way, pls let me provide my code of configure.kam and it is
shown below.
