libxml2-2.9.5 pushed into Fedora ≥ 27 introduced a bug that prevents perl-XML-LibXML package from building. libxml2's upstream fixed it with this commit: commit 3157cf4e53c03bc3da604472c015c63141907db8 (HEAD -> master, origin/master, origin/HEAD) Author: Nick Wellnhofer <wellnhofer> Date: Wed Sep 20 16:13:29 2017 +0200 Report undefined XPath variable error message Commit c851970 removed a redundant error message if XPath evaluation failed. This uncovered a case where an undefined XPath variable error wasn't reported correctly. Thanks to Petr Pisar for the report. Fixes bug 787941. It would be great if you applied it to Fedora. If don't have time, I can do it.
