Attaching draft #2. I've taken account all the replies so far. I left
complex one-liners out in _purpose_, and _want to_ people not
understanding the issue to follow up in the forums post.

After upgrading from libpng14 to libpng15 it's important that you rebuild
cairo and gdk-pixbuf as soon as possible if they are installed.
Then you can proceed with rebuilding the rest of the software against the new
library:
# revdep-rebuild --library libpng14.so.14 -- --keep-going
Note: It might be necessary to run the previous command more than once.
If you find packages not building with the message "ld: cannot find -lpng14",
they are likely caused by broken libtool archives (.la) in your system.
You can identify those files with following one-liner:
# find /usr/ -name '*.la' -exec grep png14 {} +
Ocne you have identified the broken files, you can either delete them,
edit them in place and replace png14 with png15, or re-emerge the packages
they belong to.
