Mattias,

I got it installed! 8-). The problem I had was with a bunch of 
fp-*-3.0.0 packages that were not removed when I uninstalled 1.6.2 and 
fpc 3.0.0.  They did not show up in any of the gui package managers 
either.  Only when I tried to install 3.0.4 was the fp-compiler-3.0.0* 
shown in the error messages.  I removed it and another fp-* package was 
reported.  I finally had to remove each of them individually (about 10 
or 12), then log out and back in (I think that cleared some kind of 
cache, but that is speculation on my part).  I was finally able to 
install fpc 3.0.4 and lazarus 1.8RC5.

So far it looks good.  Now I have to install all my components, then 
resume work on my current project (as a guinea pig for RC5).

Thanks for the help.
