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

[Karl Berry]

    ../../../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've forwarded your message to Peter Breitenlohner, who did that work.
He's not on this list.

(FYI, tlbuild at tug.org is a better list for build-related issues, but
it's ok to post here too.)

Thanks,
Karl
