dpkg-shlibdeps: warning:
debian/python-gdcm/usr/lib/python2.7/dist-packages/_gdcmswig.so
contains an unresolvable reference to symbol PyObject_IsTrue: it's
probably a plugin.
dpkg-shlibdeps: warning: 86 other similar warnings have been skipped
(use -v to see them all).
This one is easy. _gdcmswig.so has a SONAME. This is unusual (and almost
always unnecessary) for Python extension modules and confuses
dpkg-shlibdeps. Quoting the manual page: “The indicated symbol has not
been found in the libraries linked with the binary. The binary is most
likely a plugin and the symbol is probably provided by the program that
loads this plugin. In theory a plugin doesn't have any SONAME but this
binary does have one and as such it could not be clearly identified as
such. However the fact that the binary is stored in a non-public
directory is a strong indication that's it's not a normal shared
library.”
Get rid of the SONAME and they'll go away.

I suppose these are about CLI stuff, not about Python stuff.
dpkg-shlibdeps: warning: symbol PyLong_FromUnsignedLong used by

What is the purpose of this library? I see that
package-name-doesnt-match-sonames and shlib-without-versioned-soname
were overridden without a comment.
It doesn't directly address your problem, but:
- If it's a general-purposed library that is supposed to be used by
other packages, then it should be versioned, put into a package with
versioned name, and linked to all the libraries it uses symbols from.
- Otherwise, it should be moved to a private directory.
