+Subject: [PATCH] xapian-bindings: Fix the build with slibtool
+
+With slibtool the --config argument works differently than in GNU
+libtool which results in 'auto/Xapian/Xapian$(PERL_SO)' failing to be
+created. This can be worked around by using libtool --mode=install where
+slibtool can copy the module to the intended location.
+
+However GNU libtool still requires using --config otherwise it fails
+during --mode=install with the following error.
+
+  /bin/bash ../libtool --mode=install cp Xapian.la /home/runner/work/xapian/xapian/perl/auto/Xapian/Xapian.la
+  libtool:   error: error: cannot install 'Xapian.la' to a directory not ending in /usr/local/lib/x86_64-linux-gnu/perl/5.26.1/auto/Xapian
