Issues installing vshell on linux

[urisc]

Hello,

I am running redhat enterprise v4 update 3 with glibc v2.3.4
I want kerberos support and therefore need libgssapi-kerb5.so & libgssapi.so
I have the rpm for those, but it says i need glibc v2.4, which i dont have.
I haven't found it anywhere.
Any ideas? maybe there is a gssapi rpm for my version?

Thanks,

Uri
