[R] Error loading libraries in MAC

[Matthew Keller]

HI Mayte & Gregory,

This is probably a question needing to be posted to r-sig-mac. A
search for this problem on that forum turns up lots of hits. I think
everyone is having these problems (which makes me pause about whether
to switch to Mac, given how much I use R). Below is a message from the
r-sig-mac forum from R/Mac guru Simon Urbanek:

Yes, indeed, R 2.5.0 doesn't need the 4.0.3 compilers anymore and
thus no path changes. Unfortunately this seems to have influenced the
2.4 builds process. A hot fix is to install gcc4.0.3 from the full
image of R 2.4.1 (open the installation image, click on "Packages"
and then "gcc4.0.3" to install) or to use R 2.5.0 RC instead. I'll
see if I can find the culprit in the meantime...
