Jeff,
Sorry for the delay, but your email appeared in my mailbox today (Sept 1).
This is a 64bit issue, which may or may not be unique to Ubuntu (I have
never used an other 64bit distro). It turns out that /usr/lib64 is
directory that links to /usr/lib, so R thinks all of the directories are
installed twice, but there is only one version on your machine. Why
there are two directories, I don't know. My guess is that some code
looks in /usr/lib64, other in /usr/lib knowing it is a 64bit system.
It is annoying on the R end of things, but necessary for the system.
Hope this helps,
Michael
