I tried to give CPPFLAGS the value -D__sparcv9, the compiler complaint about "cross compiling". And then I tried CPPFLAGS="-D__sparcv9 -U__sparcv8", export it, installation of curl-7.21.2 is fine, but give me just the 32-bit result. Any hint will be appreciated to buil the 64-bit curl (only then

Thank you both for your reply. After reading your responses, I removed the existing CSWcurl, and compiled curl-7.21.2 from source using solstudio (the same compiler I got R-2.12.0 in place) to /opt/csw. Tried to install RCurl, I got the same error, the only difference is the include file's line
