Bug#581818: luatex: zlib version check too strict

[Török Edwin <edwintorok@gmail.com>]

Package: luatex
Version: 0.60.1-1
Severity: normal

If I install zlib1g 1.2.5 from experimental I get this error when running
luatex:
PANIC: unprotected error in call to Lua API (zlib library version does not match - header: 1.2.3.4, library: 1.2.5)

I think the version check is too strict, it would suffice to check for 1.2.x.
Why would luatex need to be rebuilt everytime zlib version is changed?
