I will defer evilness judgements to others...

The variable ${shlibs:Depends} is substituted with the the dynamic-linked
libraries as found by the step in the rules file that calls debstd
(or dh_shlibdeps, if you use debhelper).
You are statically linking (see below), so there are no shared libs to find,
so the variable stays empty, so lintian complains.
To quell the error you must compile and link this program dynamically.

dpkg-shlibdeps is not finding any dynamic libs. dpkg-gencontrol is
wigging out because it didn't get the info it needs from dpkg-shlibdeps.
You should get a file in the debian directory (after running build)
named 'substvars' that has the string to substitute for ${shlibs:Depends}
If seems the upstream author decided to statically link all the libraries
rather than worry about dependancies and possibly getting bug reports
because his users did not have the required libraries.
Because of the wonderful dpkg, you don't have to worry about that...
You can explicitly specify which libraries are needed and be assured
that they exist on the user's machine.
I suggest you read the gcc documentation about dynamic/static linking.
(look at the -fPIC option), change the makefile to link dynamically,
and your lintian problems will disappear!
Good luck,
-Mitch
