"of course"? R is normally (i.e. from CRAN) installed so that admin users can modify settings. It will only fail if you messed with sudo before or you are not an admin user.

You have to build rJava from sources with R64 because Oracle's Java is incompatible with anything Apple has supplied before -- see the Oracle 1.7 thread on stats-rosuda-devel (which is the mailing list for rJava and JGR). Oracle's Java doesn't support 32-bit anyway, so you have to use 64-bit R.

There is no compiler involved in iplots and there is no reason to mess with it (you were mistaken, iplots merely starts rJava which is where you get the JVM error - it has nothing to do with iplots, really) - there is no native code in there and it works with any Java, so just use the CRAN binary. The only piece you have to re-compile is rJava (and possibly JavaGD), everything else should work from CRAN. Just make sure you're using the 64-bit JGR launcher.
