GLIBC version

[Pierre Abbat]

I'm getting a GLIBC version error running some, but not all, of my Linux 
binaries on DragonFly. Here are the outputs of ldd on two of them:

rainsim/debug/src/rainsim:
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x28063000)
        libm.so.6 => /lib/libm.so.6 (0x2813f000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x28166000)
        libc.so.6 => /lib/libc.so.6 (0x28171000)
        /lib/ld-linux.so.2 (0x2804c000)
foncvrate/debug/src/foncvrate:
foncvrate/debug/src/foncvrate: /lib/libc.so.6: version `GLIBC_2.4' not found 
(required by foncvrate/debug/src/foncvrate)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x2806e000)
        libm.so.6 => /lib/libm.so.6 (0x2814a000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x28171000)
        libc.so.6 => /lib/libc.so.6 (0x2817c000)
        /lib/ld-linux.so.2 (0x28057000)

I just compiled both of them yesterday, synced them over to the DFly box, and 
still get the error on one, but not the other. The libc.so.6 on DFly is a 
symlink to libc-2.3.5.so. I haven't updated any packages on the Linux box in 
weeks. Any idea what's happening?
