+Subject: [PATCH] Ticket #4070: misc/Makefile.am: install mc.lib only once.
+
+Before the change mc.lib was installed twice due to being
+in two _DATA variables:
+
+dist_pkgdata_DATA = \
+ mc.lib
+
+pkgdata_DATA = \
+ $(dist_pkgdata_DATA) \
+ $(PKGDATA_OUT)
+
+This causes occasional install failures when two parallel
+`/usr/bin/install` calls race in installing the file:
+
+$ make -j20 DESTDIR=/var/tmp/portage/app-misc/mc-4.8.24/image install
+...
+ /usr/lib/portage/python3.6/ebuild-helpers/xattr/install \
+ -c -m 644 mc.lib '/var/tmp/portage/app-misc/mc-4.8.24/image/usr/share/mc'
+ /usr/lib/portage/python3.6/ebuild-helpers/xattr/install \
+ -c -m 644 mc.lib mc.charsets '/var/tmp/portage/app-misc/mc-4.8.24/image/usr/share/mc'
+...
+ /usr/bin/install: cannot create regular file
+ '/var/tmp/portage/app-misc/mc-4.8.24/image/usr/share/mc/mc.lib': File exists
+
+After the change mc.lib is present only in dist_pkgdata_DATA.
