You know this is not actually doing what you think it is because you
have created a chicken+egg problem. When you do "rpmbuild -ta" RPM,
RPM has no knowledge of what %name and %version should be when extracting
the .spec files from the tar.gz. As a result you'll see it has actually
created a directory literally called "rpmbuild/%{name}-%{version}" and
put virt-manager.spec there.

$ rpmbuild -ta src/fedora/virt-manager/virt-manager-0.9.5.tar.gz
error: Unable to open /home/berrange/rpmbuild/virt-manager-0.9.5/virt-manager.spec: No such file or directory
$ ls ~/rpmbuild/
BUILD  BUILDROOT  %{name}-%{version}  RPMS  SOURCES  SPECS  SRPMS
$ ls ~/rpmbuild/%\{name\}-%\{version\}/
virt-manager.spec

Evidentally when it then tries to run the build, %name and %version
be expanded causing rpmbuild to look in "rpmbuild/virt-manager-0.9.5"
for the spec file, which is obviously not where we just saved the
file.

I don't know why this works for some archives and not others though.
I'd expect all of them to be broken with the way you configured your
macros.

Daniel
