hello people, I try to configure qjackctl-0.2.2-2 on debian lenny and I get checking whether QTDIR environment variable is set... no configure: error: QTDIR must be properly set. Spent quite a time on google by now, but none of the solutions changed anything. on this list I found the hint to set QTDIR=/usr/share/qt3 somewhere else QTDIR=/usr/include/qt3 or QTDIR=/usr/lib/qt3 but neither changed anything. The header-files (if its them, the configure-script is looking for) are actually in /usr/include/qt3, libqt3-headers, libqt3-mt-dev and qt3-dev-tools, all version 3:3.3.7-4, are installed. would not mind installing qjackctl via apt-get, but: The following extra packages will be installed: libjack0.100.0-0 I manually installed (and need) jack-audio-connection-kit 0.103.0-1 (with checkinstall) - don't think it is a good idea to say yes here. Am I missing something very basic? in any case i would like to learn more.
