If you grab the .deb installation files from the download links and attempt to install them on Debian stable (Wheezy), remember that CQRLog is developed on Ubuntu, which is tracking Debian testing (Jessie).  With each Ubuntu release, the differences between Ubuntu and Debian increase.

To install these .debs on Wheezy you need to edit the control file a bit to account for some naming changes and a version change in pango that occurred in testing.

First, download the .deb for your architecture and move it into it's own folder.

For the amd64 version, create a batch file or copy and paste as so:

ar x cqrlog_1.8.3-1_amd64.deb
tar -xzf control.tar.gz
sed -i s/libpango-1/libpango1/g control
sed -i s/libpangocairo-1.0-0\ \(\>=\ 1.14.0\)/libpango1.0-dev\ \(\>=\ 1.30.0\)/g control
tar -c postinst postrm md5sums control | gzip -c > control.tar.gz
ar rcs cqrlog_1.8.3-1_debian_amd64.deb debian-binary control.tar.gz data.tar.xz

Now you can install the cqrlog_1.8.3-1_debian_amd64.deb file without errors.

If you are running i386, the script is as follows:

ar x cqrlog_1.8.3-1_i386.deb
tar -xzf control.tar.gz
sed -i s/libpango-1/libpango1/g control
sed -i s/libpangocairo-1.0-0\ \(\>=\ 1.14.0\)/libpango1.0-dev\ \(\>=\ 1.30.0\)/g control
tar -c postinst postrm md5sums control | gzip -c > control.tar.gz
ar rcs cqrlog_1.8.3-1_debian_i386.deb debian-binary control.tar.gz data.tar.xz

And again, install the new .deb without errors.

Enjoy!
