[R-SIG-Mac] FW: [R] Mac OS X 10.2.8 versus 10.3.4 package load failure

Hello All,
I had sent the following question to R-help:

To which Brian Ripley replied  "the problem is that you compiled the code
with wide characters, and on your 10.2.8 the support functions are not
compiled into the R binary (which is what I would expect)."

Has anyone had similar problems? and solved them?

In particular, what can i do about these wide characters?

regards, ingmar visser
