The default minimum supported version in GCC is the last release 
that supported PPC, i386 and x86_64.  So it could be that you're 
misremembering 10.4; I think the Mac-mini I have is 10.6, though 
not too sure about that.  The only certain thing I know is that 
it's too old to be upgraded to a newer version. :-)
