The autoconf build system for poppler does not support building the
wrappers separately, so this slightly enlarges the size of closures. To
compensate, the command-line utilities have been separated into their
own package.

KDE 4. This also ensures that kdeApps and kde4 are using the same
version of kdelibs; different versions appear to be causing integration issues.
