The glibc version is 2.5, if I believe the changelog, along with:

    ramsay$ ls -l /lib/libc.so.6
    lrwxrwxrwx 1 root root 11 2007-06-24 19:44 /lib/libc.so.6 -> libc-2.5.so*
    ramsay$

... but the header files tell a different story:

    ramsay$ grep 'define     __GLIBC_' /usr/include/features.h
    #define __GLIBC__       2
    #define __GLIBC_MINOR__ 4
    ramsay$

The distro is Ubuntu (but I can't remember which version; I would have to re-boot to find out so ...).

HTH
