We currently support releases of Linux that are of ~RHEL5 and later. This proposal drops RHEL5 support for 6.0.0. This gives us (in particular) better Bison and OpenSSL minimum requirements, such that we can keep the code cleaner.
The Jira for this is https://issues.apache.org/jira/browse/TS-3107 Unless we hear otherwise within 1 week, this will be implemented for 6.0.0. We will update the Wiki with the library version dependencies (see below). — Leif The package requirements for RHEL6 are: gcc-4.4.7-11.el6.x86_64 openssl-1.0.1e-30.el6.8.x86_64 bison-2.4.1-5.el6.x86_64 pcre-7.8-6.el6.x86_64 hwloc-1.5-3.el6_5.x86_64 libxml2-2.7.6-17.el6_6.1.x86_64 tcl-8.5.7-6.el6.x86_64 zlib-1.2.3-29.el6.x86_64 libcap-2.16-5.5.el6.x86_64 xz-libs-4.999.9-0.5.beta.20091007git.el6.x86_64 glibc-2.12-1.149.el6_6.5.x86_64
