[gentoo-user] --buildpkg and doing a dry run on a upgrade

[Dale]

Hi,

I'm wanting to install the latest KDE 4.5 which is in the kde overlay.  
I got everything unmasked, keyworded and ready to go.  Since this is a 
large upgrade and will take some time to compile, I would like to just 
build the binaries then come back and install them when the compiling is 
all done.  The emerge man page says this:

--buildpkgonly (-B)
Creates binary packages for all ebuilds processed without  actually  
merging  the  packages.   This comes with the caveat that all build-time 
dependencies must already be emerged on the system.

The part that I have a question on is the dependencies.  Will portage be 
able to build all the packages when the previous packages are not 
installed yet?  My thinking says this won't work but looking for a 
second opinion from a more "seasoned" guru.

Thanks.

Dale
