LD_PRELOAD and dlopen

[Stephen Done@home]

Hi Andreas,

That did indeed fix the problem. If you have time, could you give a very
quick explanation of why, and also perhaps why gcc acted differently under
Solaris with the 'undefined versioned symbol name dlopen@@GLIBC_2.1' error.

Thanks again

Steve
