-- the two lines that delete the package installation receipt need correcting for the Privoxy version being built
+There are two important further considerations that this approach brings. Firstly, you must ensure when building PCRE that you build it to support the same minimum version of OS X that you wish Privoxy to support (note that by default PCRE will assume the OS X version of the build machine is the minimum version to be supported). Failure to observe this will mean that, whilst Privoxy will still build, the external PCRE check will fail and you will end up compiling in the bundled PCRE, not linking to the external PCRE library as you'd intended.
+
+The second consideration when using external PCRE is that the PCRE build process allows only single-architecture libraries to be built; the corollary being that your Privoxy binary must also be single-architecture. The outcome of not following this rule would be as above; you will succeed in building Privoxy but it will compile in the bundled PCRE rather than linking to the external library.

+
+2. Construct the package contents hierarchy
+
+Use constructPkgContent.sh to build the hierarchy of folders and files necessary for building the package. This will construct a new folder named 'pkg content' and copy in the binary, documentation and supporting files. If you are bundling an external PCRE fileset, use the optional switch -pcre to instruct constructPkgContent.sh to include those files.
+
+Once this is done, the file 'pkg resources/interface texts/ReadMe.txt' will need to be edited to give a precis of what this release of Privoxy brings. This can be distilled from the README for the latest Privoxy project release.
