dump-0.4b22-4.src.rpm  or even dump-0.4b19-5.6x.src.rpm will not appear to rebuild on 
RHL62.  Errors include, but are not limited to:

/usr/bin/../lib/libext2fs.a(llseek.o): In function `ext2fs_llseek':
llseek.o(.text+0x55): the `llseek' function may be dangerous; use `lseek64' instead.

Upgrading to rawhide e2fsprogs, e2fsprogs-devel, readline, readline-devel fixed this.

As rebuilding rawhide dump works on unmodified RHL7.0, I suggest adding required versions:

BuildPrereq: e2fsprogs-devel, libtermcap-devel, readline-devel

to:

BuildPrereq: e2fsprogs-devel >= 1.18, libtermcap-devel, readline-devel >= 4.1
