Well, I can install and run  RCurl  on both 32bit and 64bit
(Redhat / FC6  Linux; with own compilers, extra libs, ...).

You might need to set  LD_LIBRARY_PATH  correctly
before starting R -- typically it would be set the same as it
was when RCurl was installed (which includes a 'configure' !) on
your system?  Or  RCurl's configure is not quite robust enough
and did not check for the presence of a libcurl.so.4

I assume

  ldd /share/apps/R/R-2.4.1/library/RCurl/libs/RCurl.so

also tells about the missing  libcurl.so.4 ?
Make sure you find that (in /usr/lib; /usr/local/lib, ... ?)
and then set your LD_LIBRARY_PATH
or even   'ldconfig' as root to make sure that libcurl.so.4 ``is
found''.
IMO the latter {correct ldconfig call / /etc/ld.so.conf setup}
should have happened as part of the installation of the curl
library.

On the 64-bit architecture, note that

 > system(paste("ldd", dir(system.file("libs", package = "RCurl"), full=TRUE)))

finds all libraries in /lib64 and /usr/lib64 .
