Perl is necessary to our build processing, it will invoke a lot of

ok for build from git checkout, because autogen.sh will tell you.
But for compiling from a release tarball, configure will just record
a missing message, and continue, then build failed, like:
https://www.redhat.com/archives/libvirt-users/2014-August/msg00050.html
So need to enhance configure script to handle this negative case.

I'm inclined to ACK this. We currently have some files that can be
built from git and are contained in the release so we cut off the set
of required tools to build the libvirt. However, with so widely
accessible tool as perl (which is almost everywhere) we don't need to
do that. Moreover, there are some Makefile targets which have runtime
dependency on perl, e.g. bracket-spacing-check syntax-check rule.
And with this change I think we need this one too:
Yes, the BuildRequires should also be added in libvirt.spec.in.
Thanks for the review both of you.

Again, I'm not expecting to see any RPM based distribution without
perl (esp. if rpm-build package requires perl itself). But we should
have it for completeness.
So I'm squashing it in and pushing.
ACK
