In case it's of interest to anyone, I went through the checklib logs
available on the web page for "problems" and found the libraries that
are most often listed as bogus dependencies. Here are the top twenty
offenders, listed with the number of packages that (according to
checklib) have each as an unnecessary dependency:
1663: libxext6
1275: libxi6
1196: zlib1g
1174: libx11-6
949: libice6
948: libsm6
940: libfontconfig1
923: libxrender1
918: libxinerama1
918: libxcursor1
905: libxrandr2
697: libatk1.0-0
688: libcairo2
636: libgcc1
610: libxfixes3
536: libpango1.0-0
480: libpng12-0
424: libfreetype6
394: libart-2.0-2
386: libxml2
Most of these are X-related, suggesting that quite a lot of .la and .pc
files are pretty indiscriminate about which X libs they link in.
I used the attached (fairly trivial) script to scan through the log
files. It is pretty dependent on the exact file format of the logs, though.
