ports. Several ports do not compile anymore (inkscape, libreoffice,
libxul, to name some of the very hurting ones!).
Someone forced you to recompile your ports? :)
Just for the record, I too saw a lot of re-compilation necessary because
of this PNG library update and for the most part, this was not
necessary, but unfortunately this is how the ports dependencies are
described by their maintainers - the upgrade tools like portmaster or
portupgrade can hardly help much here.
Anyway, I am rebuilding on occasions like this just for the fun of it.
Always have spare/backup system to work on while my primary desktop
rebuilds because it breaks from time to time. By the way, this rebuild
didn't give my lowly dual-core core2 6300 at 1.86 GHz much trouble.
In any case, suppose a customer comes and asks for an application that
uses PNG, you just updated your ports tree and then you either:
1. Have already libpng installed.
Then you just don't rebuild libpng, just install the new software. You
do this by going to the ports directory like
/usr/ports/cathegory/greatstuff and type "make install". This will use
the existing libpng on your system. No trouble.
2. Don't have libpng installed yet.
You install the new port any way you like. Since you have no libpng on
your system, you have no dependencies to upgrade (and wait). You will
end up with the new libpng on your system. No trouble.
Applying some common sense to these situations helps great deal. It also
helps to avoid any prejudice towards FreeBSD or whatever OS you end up
using in the process.
