I also think it's not necessary to create new build root in this case.

The last buildroot override problem has been caused by incompatible perl-libs.
This is not this case and atomicity of git pushes and ordering of binary
package versions should cope with buildroot merge fluently.

Marcela forgot to explain the real problem:

There are packages that install private data into perl include path. If you
compiled such package with install=vendor in F14, the private data got into
/usr/share/perl5/ because vendor and core paths resolved into the same
directory.

The problem is some packages do not store absolute path at compile time. They
store just the symbolic name (vendor or core) and resolve it at run-time (e.g.
via Config module).

If you run such package, built in F14, in F15 where vendor path points to
/usr/share/perl5/perl_vendor, then the package will look it's private data in
/usr/share/perl5/perl_vendor, but the files will be located in
/usr/share/perl5/ in the binary package.

Thus we need to recompile all binary packages survived from F14 to move their
files to actual vendor path.

We would like to edit all spec files to switch from vendor to core in the
future. But not now.

Fortunatelly there is no need to hurry as properly compiled packages
work regardless residing in core or vendor as you mentioned. (Except the few
packages having the problem I described above). So we would like to
standardize the install path in Perl guidelines first, that adjust cpanspec and
rpmlint and then advise packagers to fix their specs as they touch them for
other reason.

In other words we are not going to change spec files in this mass rebuild. We
just want to rebuild the packages to fix the current issue.

Question whether to massively rewrite vendor to core install path in next
massive rebuild planned for perl-5.14 is not decided yet.
