Yes you are.
I work with Solaris 10 i386, and i build it :

[root@redhot 769] file /usr/pkg/lib/libbz2.so*
/usr/pkg/lib/libbz2.so: ELF 64-bit LSB dynamic lib AMD64 Version 1, dynamically 
linked, not stripped, no debugging information available
/usr/pkg/lib/libbz2.so.0:       ELF 64-bit LSB dynamic lib AMD64 Version 1, 
dynamically linked, not stripped, no debugging information available
/usr/pkg/lib/libbz2.so.0.0.0:   ELF 64-bit LSB dynamic lib AMD64 Version 1, 
dynamically linked, not stripped, no debugging information available
[root@redhot 770]

That's really a true problem, Solaris is not 'symetric' for different ABI.
The best way is Sun provide thoses libraries as their marketing would pretend.
About libXau and libXdmcp (ABI=64), I build them with pkgsrc (xorg-libs), but my
work is not clean (as usual...).
If you want it, i will send it.
