Thank you Hal for your response, but something seems to be wrong on 
ubuntu breezy since I can't launch PTStitcher out of the i386_chroot, 
on amd64 ubuntu/breezy I get this:
gerhard at ubuntu:~/download/panorama$  PTLinux/Helpers/PTStitcher

Ok, I did now $ apt-get install ia32-libs-dev
but it doesn't helps.

The simple (?) question is:
How to link ia32 libs the right way, even if they are symlinks to the 
right libs.

$ sudo /sbin/ldconfig -v -l /usr/lib32/libpng.so.2
/sbin/ldconfig: Ignored file /usr/lib32/libpng.so.2 since it is not a
regular file.
$ ldd PTStitcher 
        libpng.so.2 => not found
$ ldconfig -p |grep png
        libpng12.so.0 (libc6,x86-64) => /usr/lib/libpng12.so.0
        libpng12.so.0 (libc6) => /usr/lib32/libpng12.so.0
        libpng12.so (libc6,x86-64) => /usr/lib/libpng12.so
        libpng10.so.0 (libc6,x86-64) => /usr/lib/libpng10.so.0
        libpng10.so.0 (libc6) => /emul/ia32-linux/usr/lib/libpng10.so.0
        libpng10.so.0 (libc6) => /lib32/libpng10.so.0

So, how to get libpng.so.2 (libc6) =>  /usr/lib/libpng10.so.0 ?

$ cat /etc/ld.so.conf
/usr/X11R6/lib
/emul/ia32-linux/usr/lib
/emul/ia32-linux/lib
/lib32
/usr/lib32
/usr/X11R6/lib32
/usr/local/lib
/usr/lib/pango/1.4.0/modules/
/usr/lib/GNUstep/System/Library/Libraries
