RedHat < 7.0 still uses libc 2.12 as far as I'm aware. Pharo 5 has a downloadable version that works on that OS. OEL with the UEK has an updated libc.

Which OS has such old versions of LibC? Which LSB standard does it support?
Hi, This is RedHat. I don't have the right to give more info than the fact it is a RedHat with a LibC version < 2.15. I don't know for the LSB support. I can ask but I will probably not know before the end of next week.
