#pkgsrc puts a fair amount of effort into helping packages use external packaged dependencies, rather than bundled copies of third party source
Which was really handy just after libwebp's 1.3.2 #zeroday fix recently
% pkg_info -n libwebp
[ 48 packages using the updated libwebp, including libreoffice, qemu, thunderbird, five web browsers, calibre, filezilla, roundcube, audacity, gimp and more ]
Remind me again why bundling packages up with a private copy of all their dependencies is better?
