That's the argument in favour for using --with-system-libs and its
definitely the right choice for distros. Little bit trickier when
putting on a ISV hat and trying to target all Linux distros

Windows. For Linux, yeah zlib and jpeg and a few others are definitely
indefensible.

Sure, and the xpdf thing is a bit of a disaster as well.

What's the target distro that the universal build on e.g. the website
download site should pick. Hard choice. That's the catch. Pick e.g.
RHEL-6 and the packages can't work on RHEL-5 seeing as they have
different icu versions and so on. We should nail the easy ones anyway,
but I don't think we can nail *all* of them.

We also definitely need to update to the latest stable versions of all
the libs-extern/libs-extern-sys that we do have.
