A debian package normally build-depends on the development package
providing the development files (headers, pkg-config, (unversioned)
shared object file, etc.) rather then simply on a package with only
a particular versioned .so.X.

In other words, build-dependencies should normally end with -dev
(if it's a library and not a tool used during the build process).

The above list would be more correct as:
libaugeas-dev,
libcap-dev,
libhivex-dev,
libpcre3-dev,
libxml2-dev,
libyajl-dev,


All of these are probably pulled in indirectly via some other
build-dependency right now but should be explicitly specified if
they really are build-dependencies of libguestfs.
The above -dev packages also specifies a dependency on their
respective libfooX package as needed.

Doing this correctly is what makes it possible to do binNMUs
when there's a transition for a certain library (ie. it gets
a new so version). Doing this incorrectly makes that impossible.
