Hi Nigel. Might you be able to make a precompiled frontend available?
I have an old iBook G3 running at the moment and I have not had much
success running mythfrontend in Gentoo on this box (yet). It would be
neat if I could try it out in Mac OS X, but I don't that the harddisk
space for the development kit that Apple provides (at least it would be
a very tight squeeze).
