Is it possible that PCRENATIVE=yes fails because there are only shared
libs, libpcre.so, available?

This is done by the specfile for the rpm package build process.

I think my problem was not specifying absolute paths from root.

See above.

I should at least be able to build with the unixbuild.sh script once
I've fixed the path problem. One possible problem though is, it uses
it's own libxml and not pcre. Another possibility is, I'm building on an
x86_64 system with a lib and lib64 directory, maybe it's not in the
search path or something. I did try making a link libpcre.so in /lib to
/lib64/libpcre.so.0.0.1
