xmlcharent-0.3_2 and iso8879-1986_3 package reinstalls: "pkg: POST-INSTALL script failed"?

[Mark Millard]

In updating a powerpc64 context after a poudriere-devel bulk run, I
got the following from pkg upgrade . . .

Installed packages to be REINSTALLED: 	xmlcharent-0.3_2 (ABI changed: 'freebsd:12:powerpc:64' -> 'freebsd:12:*')
. . .
	iso8879-1986_3 (ABI changed: 'freebsd:12:powerpc:64' -> 'freebsd:12:*')
. . .

[127/181] Extracting iso8879-1986_3: 100%
xmlcatmgr: entry already exists for `/usr/local/share/sgml/iso8879/catalog' of type `CATALOG'
pkg: POST-INSTALL script failed

. . .

[138/181] Extracting xmlcharent-0.3_2: 100%
xmlcatmgr: entry already exists for `/usr/local/share/xml/xmlcharent/catalog' of type `CATALOG'
xmlcatmgr: entry already exists for `/usr/local/share/xml/xmlcharent/catalog.xml' of type `nextCatalog'
pkg: POST-INSTALL script failed

The context is a personal head-based -r339076 buildworld
buildkernel (it was cross built) and ports being updated
based on -r480180 .

Is there anything that I should do because of the messages?
