Hi,

apache will not start (service apache24 start) and this appears in httpd-error.log:

ld-elf.so.1: /usr/local/lib/php/20210902/mbstring.so: Undefined symbol "php_pcre2_compile"

This error appeared after upgrade from php81-8.1.25 to php81-8.1.26_1 and all dependencies.
The error persists after rebuilding all php ports with 
poudriere bulk -j 132Ramd64 -O sccache -C -f php-portslist.txt

more context:
apache24-2.4.58_1

# freebsd-version -kru
13.2-RELEASE-p4
13.2-RELEASE-p4
13.2-RELEASE-p7

all ports are built in poudriere-devel:
