Well, the last official version of AMX is indeed 0.9.3. But the unofficial 0.9.8 version is available both for glibc2.3 and glibc2.2:

Alternatively there is
AMX Mod X which is actively developed. But this still has some problems. They claim that simply recompiling AMX plugins would make them work for AMX Mod X but that's sadly not true. I tried it yesterday and most of our plugins failed to work as expected...
At the AMX Mod X site they maintain a modified version of MetaMod which has all resend changes and fixes. They also send those changes to Will Day who hopefully put them into the next official release.
