The same happens for me with cleared autoconf cache:

checking for getnameinfo... yes
checking for pcre_compile in -lpcre... yes
checking for pcre.h... yes
configure: WARNING: pcre old version installed
checking for regcomp in -lpcreposix... yes
checking for pcreposix.h... yes
checking for pcre2_compile_8 in -lpcre2-8... yes
checking for pcre2.h... yes
configure: WARNING: pcre2 old version installed
checking for regcomp in -lpcre2-posix... yes
checking for pcre2posix.h... yes
configure: WARNING: pcre2posix old version installed
Enabling support for client-specific tags.
checking for zlibVersion in -lz... yes
Enabling compression support.
configure: error: pcre2 or pcre library not detected.
