You do not understand the problem here; as the last incarnation
I looked at, it was indeed completely useless for things like fvwm --
since it worked on a binary by binary basis, instead of a per package
basis. Since we do build depends on a package by package basis, looking
at dependencies of individual binaries is not good enough.
Say a package as bin-foo, bin-bar, and bin-baz. They build
depend, respectively, on libfoo-dev, libbar-dev, and libbaz-dev,
When checklibs was run, it would report
libbar-dev, libbaz-dev, unneeded; looking at foo
libfoo-dev, libbaz-dev, unneeded; looking at bar
libfoo-dev, libbar-dev, unneeded; looking at baz
End result: Uneedded: libfoo-dev, libbar-dev, and libbaz-dev
Since that is patently wrong, the version of checklibs I looked
at produced meaningless output -- for any package that had shared
objects whose compile flags were not identical.

Er, why? I have a working version that works on a package basis,
not on a binary by binary basis, and it was a few lines of simple shell
scripting. Also, if I recall correctly, the original script was in
python. I don't do python.
The original site where I got the old implementation
(http://greek0.net/div/checklib.tar.gz) from is 404's now; the alioth
checklib project has published nothing. First rule of free software:
publish early, publish often.
During the voyage of life, remember to keep an eye out for a fair wind;
batten down during a storm; hail all passing ships; and fly your colors
