in reply to Perl QtCore4 won't install

That distro is outdated. Check out code from the official repository instead. You didn't say what version of Qt you are running, so I'm linking to the main branch.

As with any C-library, you need the appropriate header files from the packages libsmokeqt-devel and libqt4-devel at the least. These are the OpenSUSE names, you need to figure out the debianised equivalents yourself.

    Thanks daxim. I'm not sure I understand how qtcore4-0.99.0 is an older version than qtcore4-0.96.0. Or were you referring to another library? I have installed the debian packages (libqt4-dev, libsmokeqt4-dev) and loads more I have qt 4.8.2 installed. From here when I try

     cpan QtCore4

    it tries to build smokeqt I think, and fails here:
