Ting-Wei Lan <lantw44 at gmail.com> has reassigned Bugzilla Automation
<bugzilla at FreeBSD.org>'s request for maintainer-feedback to ruby at FreeBSD.org:
Bug 219418: textproc/rubygem-nokogiri: fails to build with elfutils installed
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219418



--- Description ---
devel/elfutils port installs a shared library called libelf.so.1, causing the
linker to print warnings when linking test programs.

/usr/bin/ld: warning: libelf.so.2, needed by /usr/local/lib/libruby23.so, may
conflict with libelf.so.1


This causes pkg_config function call in ext/nokogiri/extconf.rb to return nil,
so it fallbacks to rubygem-pkg-config. However, the rubygem-pkg-config 1.2.0
provided by ports cannot pass the version check.

gem 'pkg-config', (gem_ver='~> 1.1.7')
