Is the check of zlib version essential? I googled a fix that remove zlib version in gentoo. http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-tex/luatex/files/remove-zlib-version-check.patch?view=diff&r1=text&tr1=1.1&r2=text&tr2=1.1&diff_format=s However, according to the zlib changelog(http://zlib.net/ChangeLog.txt), the release with a major version change, such as 1.2.7->1.2.8, was not so often. So I am fine with downgrading zlib manually, considering the low frequency. On 5/24/2013 3:52 AM, Ken Brown wrote: > That's annoying.
