32bit libs without the 32bit chroot

[Jiri Barton <jbar@hosting4u.cz>]

Hi,

I'm trying to set up printing on Lexmark Z612. This beast has a binary driver 
only, available from Lexmark (actually, the driver is for the model Z600). 
After extracting the files from the RPMs to the appropriate directories, I 
got it almost working, except

[root@balmora /usr/lib]# ldd /usr/lib/cups/filter/rastertoz600
        linux-gate.so.1 =>  (0xffffe000)
        liblexprintjob.so.0 => /usr/lib/liblexprintjob.so.0 (0x55583000)
        liblexz600core.so.0 => /usr/lib/liblexz600core.so.0 (0x55588000)
        libcups.so.2 => not found
        libcupsimage.so.2 => not found
        libstdc++.so.5 => /emul/ia32-linux/usr/lib/libstdc++.so.5 (0x55627000)
        libm.so.6 => /usr/i486-linux/lib/libm.so.6 (0x556e1000)
        libgcc_s.so.1 => /emul/ia32-linux/lib/libgcc_s.so.1 (0x55704000)
        libc.so.6 => /usr/i486-linux/lib/libc.so.6 (0x5570c000)
        /lib/ld-linux.so.2 (0x55555000)

As you can see, the drivers (the rastertoz600 binary) are 32bit only and 
therefore link to 32bit libraries. Now, the only thing I need to do is to 
install CUPS to the 32bit environment so that the executable rastertoz600 
will find it.

My question is, what is the easiest way to do that? I have not set up the 
32bit chroot but I do have ia32-* libraries installed. Is there a way I can 
install the 32bit cupsys into /emul/ia32-linux directory without actually 
going through the 32bit deboostrap? And, how can I install all the 32bit 
cupsys dependencies too?

How do the maintainers of ia32-libs-dev, ia32-libs, and the like do that?

TIA,  jbar
