Good to know.

Still, are those patches very special or could upstream provide your

As I am maintainer of erlang in Gentoo Linux, I have a bug open asking
for using system's zlib, but that is not important to you. :)
Take it that there is a security flaw in zlib. zlib in Gentoo is
updated, stabled and done. Nobody thinks of erlang (or any other
package shipping a custom version of zlib instead of linking against
the system one), so we have a possibly vulnerable version in the tree.
Which is baaaaad. Backporting patches from vanilla zlib to erlang is
just needless work in my eyes, and I have to be aware of these fixes
or even of an included library (there may be more I don't know about).
