Hello  Steve,

I suggest not to use RealOnly.
With the package loaded, there are horrible mistakes with 5.0. 
(Let us call it "bugs")

For example :

<< "Miscellaneous`RealOnly`"

Integrate[1/(x^2 + x + 1), x]

x/(1 + x + x^2)

Which is wrong, of course !

So it is better to use 
ComplexExpand     and 
and so on!

Use the Miscellaneous`RealOnly` package.
