When npm installing couchnode on CentOS 5, the precompiled binary is linked against non-standard versions of GLIBC

I'm getting the same issue on CentOS 5 with 2.1.6 as from the issue from this ticket https://issues.couchbase.com/browse/JSCBC-295. This used to work.
Uncaught exception: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by <...>/node_modules/couchbase/build/Release/couchbase_impl.node)
data:
