[gembud] GLIBC_2.4 not found message

Hi all..

Installed GEMPAK 5.10.3 and after modifying the Gemenviron file and properly sourcing GEMPAK 5.10.3 in .cshrc get the message

/lib64/tls/libc.so.6: version `GLIBC_2.4` not found (reguired by ntl)

when typing "ntl". This message also occurs for manual launching of any of the ntl programs such as nmap, garp, etc.

Some useful info:

Performing a "which ntl" gives the /internal1/peter/GEMPAK/GEMPAK5.10.3/os/linux64/bin/ntl (so its pointing to the correct location) The file /lib64/tls/libc.so.6 exists and is actually a link to /lib64/tls/libc-2.3.4.so (which also exists)

Have since reverted to GEMPAK 5.10.2 but in the meantime.. any thoughts on how to remedy this issue?
