Yes, I think it's the first step in the right direction - we need a
native OS X GUI ;). Good job, Stefano.

That should be easy to fix since there is a call to the framework to
ask where the bundle root is.

A more general question about this: the libdl is really very tiny since
all it does is it maps the usual "dfcn.h" API to Apple's API. Why not
to add this statically to the R code? I'm not sure that this really
needs to be external/dynamic code. Besides each version of the library
differs (prepending underscores etc.) - so shouldn't we simply supply
it with R in general (not just with the RAqua) like we do with pcre?

Obviously one is the GUI and the other the "regular" R (by using just
one integrated bundle this problem should disappear). Funny enough one
the the two Rs "jumps" in the dock up and down all the time until it's
tired ;). A rather technical question: How do the two processes
4) The GUI should set the option to make "quartz" the default device
(so far options(device="quartz") works quite well).
