Hi Michael,
Thanks for your response. Using the binary seems to solve partially. I am
able to install (I think!) RCurl but not able to load the library. Below is
the info you required and the error while loading RCurl.

Error: package/namespace load failed for 'RCurl'
Warning: dependency ‘Rcompression’ is not available

Seems like now I need 'Rcompression'. I googled this and found a
Rcompression package 'zlib' (http://www.omegahat.org/Rcompression/).
However the site says that "zlib for Mac OS X: zlib is already included as
part of Mac OS X".

I am wondering what to do? To my bliss, why did the previous R version
oblivious of these issues!

Really appreciate any hep.

SIncerely,
Hari
