Qt4 JPEG linkage

I am writing to this mailing list because it is specified in the
'Maintainer' entry of libqt4-gui package.

I want to ask about options the qt4 source is configured with. The
problem is that the libraries from 32-bit libqt4-gui package do not work
as expected on a 64-bit machine.

The program I'm trying to run is Skype for Linux (version,
dynamic build). After installing the ia32-libs package, still some
library dependencies were unsatisfied, with qt4 among them. I downloaded
the corresponding 32-bit packages and unpacked the usr/lib parts of the
packages into /usr/local/lib32. Then, creating an address file
in /etc/ld.so.conf.d and running ldconfig was enough to get all of the
dependencies satisfied. Though, when I ran Skype, I got everything
working except for the contact pictures - they simply do not appear.

As it is suggested here -
http://forum.skype.com/index.php?showtopic=113138 - some JPEG libraries
might be missing on my installation, or qt4 might have JPEG support
disabled. However, ldd reports no "not found" entries on Skype
executable and qt4 libraries (although no libjpeg linkage, too), and the
same Qt4 version works just fine with Skype on my second i386 machine.
Hence, my question is - what's really with JPEG in Ubuntu's qt4; what
are configure options connected with JPEG that are used in Ubuntu's
