Setup fails on any system that uses bind mounts to provide access to home
directories in several chroot environments, like this one:

halls@bruckner:~$ mount
/dev/sda2 on / type ext2 (rw,errors=remount-ro)
/home on /org/bruckner.debian.org/chroot/sid/home type none (rw,bind)
[...]

Running setup gives this error:

./instsetoo/unxlngppc.pro/01/normal/setup -v
-R:/home/halls/openoffice.org/debian/local/rsfile.txt -nogui
./instsetoo/unxlngppc.pro/01/normal/setup: absolute programpath cannot be found.

The problem is in loader.c:  __getFullPath() will only try to find the patchname
using names if it seems to be an NFS mount, where the devices of the current
directory and its parent are different:

if (status.st_dev == parent.st_dev)
{
 [...]
}
else
{
   /*
    * if this point is a mount point we have to check
    * each entry, because the inode number in the directory
    * is for the parent directory, not for the mounted file
    */
 [...]
}

However, on a bind mount, status.st_dev and parent.st_dev are the same, so the
first code path is followed and fails because the inode number in the parent
directory is for the mount point.

I have worked around this by disabling the first code path and making the second
path be used always.  It doesn't seem to be a performance problem, since this
code is only used during the setup loader.

I'll attach the patch I used to work around the problem.
