- there is a tool called "fpcdeluxe" that checks out sources and builds
FPC, and downloads the necessary binutils.
- There is a bundle of FPC with Lazarus IDE called CodeTyphon, which is also
a good star for crosscompiling.
With Mac OS X, things are always more complex, since OS X doesn't use
binutils.

or mac mini is a good investment. -John]
