[tex-live] TeX Live 2011 build fails because of LuaTeX/libpng incompatibility

Hi all,

LuaTeX build stops with the following error after its update in the
TeX Live tree:

../../../texk/web2c/luatexdir/image/writepng.w:585:19: error:
'PNG_FP_1' undeclared (first use in this function)

for a couple of days now with libpng older than 1.5.2. I found related
note to this problem here:

http://permalink.gmane.org/gmane.comp.tex.context/68142

The thing is that many distributions such as Fedora do not consider
newer libpng releases stable due to its outstanding issues:

https://bugzilla.redhat.com/show_bug.cgi?id=703063

and actually still ships stable libpng-1.2.44.

Do you think I should communicate with LuaTeX upstream to address
this? In any case I wanted to make you aware of it because of the
upcoming TL2011 release.

Thanks!
Jindrich
