System: NetBSD edge.back-street.net 7.0_RC3 NetBSD 7.0_RC3 (VMWARE-F7) #40: Sat Aug 22 22:26:51 JST 2015 taca%edge.back-street.net@localhost:/data/amd64/obj/sys/arch/amd64/compile/VMWARE-F7 amd64

>Description:
	mail/postfix-pcre dose not work with error:

	postfix/smtpd[8642]: fatal: load_library_symbols: dlopen failure loading /usr/pkg/lib/postfix/postfix-pcre.so: Shared object "libpcre.so.1" not found

>How-To-Repeat:
	Build postfix and postfix-pcre and run instead of postfix-2.11.6.
>Fix:
	postfix-pcre.so dose not link with RPATH:

	% cd /usr/pkgsrc/postfix-pcre
	% make
	...
	% cd $(make show-var VARNAME=WRKSRC)
	% ldd src/util/postfix-pcre.so 
	src/util/postfix-pcre.so:
		-lpcre.1 => not found
		-lgcc_s.1 => /usr/lib/libgcc_s.so.1
		-lc.12 => /usr/lib/libc.so.12

	Some flags for ld(1) seems to lack...
