I forgot to put the actual diff string in the bug report, it was in the 
first line of the diff:

diff -u \
  <(dpkg -c libvxl1.14_1.14.0-4_amd64.deb | \
    sed -e 's/^[^.]*[.]//;s/ ->.*//' | sort) \
  <(curl http://packages.debian.org/sid/amd64/libvxl1.14/filelist | \
    sed -e 's/^<.*>//;/^.usr/!d' | sort)

The first is the package which was built when I rebuilt the package 
locally.  The second is the filelist of the official libvxl1.14 package 
as pulled from packages.debian.org (ie. the files which get installed by 
the official package).

You have 1.14.0-8 installed.  The most recent package available is 
1.14.0-4 (cf. packages.debian.org).  Maybe this got fixed by some local 
change you have?  Or did you build the package locally and happen to 
have the required package installed which "fixes" libvlx1.14?

Yes, that is exactly the problem this bug report is about.  These are 
the only sos shipped by libvxl1.14_1.14.0-4 (amd64):

/usr/lib/libnetlib.so
/usr/lib/libtestlib.so
/usr/lib/libv3p_netlib.so
/usr/lib/libvcl.so
/usr/lib/libvnl.so
/usr/lib/libvnl_algo.so

The headers are included in libvxl1-dev though.

I'm not sure what you mean by that.  The contents of a package must not 
change based on what is locally installed.  If other -dev packages are 
required, libvxl1-dev should at least Recommend them.
