These both do a loadNamespace("tools").

Error in loadNamespace(name) : there is no package called 'Tools'

Error in loadNamespace(tools) : object 'tools' not found
Those are expected, and unrelated.

This shouldn't happen. In a previous post you listed a long list of
warnings about packages not being loaded; that's likely a serious
problem, but I don't know if it is the cause or a consequence of this
one. Something is seriously wrong with the startup. You could try
debugging setup_Rmainloop in <src/main/main.c>. to see if any warnings
are being generated there. There shouldn't be any.

So, at the end - my gut-feeling is that the error messages is not
about the arguments, but us related to the "tools:::foo".
Where should I look next? It goes a bit beyond me to know where in R
"tools:::foo" is being parsed.
Guessing here - but might be related to the switch from 32-bit to
64-bit AND that PowerPC is BigEndian rather than LittleEndian? Could
also be absolutely wrong, way off base, etc. --> shoot me down!
Thanks,
Michael
