Answer 1

--with-pcre=/usr/lib64/
…

cd /usr/lib64/ \
&& if [ -f Makefile ]; then make distclean; fi \
&& CC="cc" CFLAGS="-O2 -fomit-frame-pointer -pipe " \
./configure --disable-shared

It follows from this log that the --with-pcrepath to the PCRE sources is expected by the parameter, and not to the installed libs. And by the looks of it , that's the way it is.
