1. Just download the package and unpack it.
2. Use R INSTALL until it breaks
3. Then go to the src directory and give the gcc command below with
-Xlinker -m
4. Then use R INSTALL again
There are not two definitions associated with the same symbol after
linking. This
unpleasant hack uses the definition in Utils.o, as intended. This
situation will
persist until either Duncan puts this fix into XML or until Stefano
decides to go
with two-level namespaces for Darwin/Aqua R packages.
