GLIBC_2.4 not found

[suren]

Trying to run an application on:
freebsd# uname -a

FreeBSD freebsd.localdomain 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Fri May  1 08:49:13 UTC 2009     root@walker.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

got the following error:

./mpcs-i386-pc-linux: /lib/obsolete/linuxthreads/libc.so.6: version `GLIBC_2.4' not found (required by ./mpcs-i386-pc-linux)

sources are not available for this app, only ELF file.
any idea how to overcome?
