Yes, the version of mad-admin I had did not install the shlibs file into the 
sysroot.

According to the deb-shlibs man page, libqcontactchooserdialog.shlibs should 
look like this:

libqcontactchooserdialog 1 libqcontactchooserdialog (>= 1.0-0)


Instead, mine looks like this:

libqcontactchooserdialog 1 libqcontactchooserdialog


In other words, it's missing the version number in the dependencies field.

After I followed Tomi's directions, I have 
$SYSROOT/madde_xpkgs/libqcontactchooserdialog.shlibs.  This is new, I think.

There isn't one in $SYSROOT/var/lib/dpkg/info.

Tomi, the new dpkg-shlibdeps and xdpkg files didn't fix the problem.  I get the 
same output as before when deploying my application.

Could this be related to the location of my library?  It's in 
$SYSROOT/opt/usr/lib instead of $SYSROOT/usr/lib.
