If you are using a redhat distribution, the solution is even easier: install
the rpm `gmp' (you might also need `gmp-devel'). Both of these are in the
standard 6.0 distribution.

Hmm... FWIW, (on a redhat 6.0 system), I had zero problems either using the
binary dist, or compiling from source (I built using the 4.04 binary - sorry,
not much help, I guess!). Checking my hsc binary, I have both symbols
`__data_start' and `data_start' defined.
