[R] iplots/JGR on OS X 10.4.8

[bobp]

iMac Intel Core Duo; OS X 10.4.8; Java 1.5.0_06; R 2.4.1; JGR 1.4-14; rJava
0.4-12; iplots 1.0-5

I'm unable to get JGR or iplots to load using "library(JGR)" or
"library(iplots)", respectively. This feels like it might be a classpath or
Mac look-and-feel issue, but I'm not sure where to go with it at this point.
I've searched the fora and web to no avail.

Any pointers are appreciated.
