  [+ perl Makefile.PL INSTALLDIRS=vendor NO_PACKLIST=1 NO_PERLLOCAL=1
Alien::Build::Plugin::PkgConfig::Negotiate> Using PkgConfig plugin: PkgConfig::LibPkgConf
/var/tmp/rpm-tmp.BPeDFZ: line 49:    72 Segmentation fault      (core dumped) perl Makefile.PL INSTALLDIRS=vendor NO_PACKLIST=1 NO_PERLLOCAL=1
error: Bad exit status from /var/tmp/rpm-tmp.BPeDFZ (%build)]: [%build phase exits with an error. Using PkgConfig::LibPkgConf Perl module segfaults.]

Issue: perl-PkgConfig-LibPkgConf was built against pkgconf-2.1.0. When pkgconf was rebased to 
2.1.1, PkgConfig::LibPkgConf started to crash because pkgconf changed ABI without bumping a SONAME.
Resolution: perl-PkgConfig-LibPkgConf was rebuilt against pkgconf-2.1.1.
