as a workaround define the PCRE_FLAGS and PCRE_LIBS environment variables
export PCRE_CFLAGS=-I/usr/local/include
export PCRE_LIBS="-L/usr/local/libs -lpcre"

Thanks for your report, but this isn't actually a bug - you will need to tell configure where PCRE is installed if it isn't in the default search paths. See:

./configure --help|grep -i PCRE
