I want to use RCurl to do sftp requests. 

I installed the package and ran curlVersion().  It indicates version 7.30.0 and does not list "sftp" as one of the protocols. 

I installed homebrew and installed curl with ssh.  I also updated the symlinks so that /usr/bin/curl and /usr/bin/curl-config point to the newly installed package. 

When I run curl --version from the command prompt it indicates that the version is 7.37.0 and sftp IS a supported protocol.  However, when I run curlVersion() in R, it still indicates 7.30.0 

How do I get RCurl to leverage the newer version of curl? 

Mac OSX Mavericks 
R Version 3.1.0 


Cheers,

JP
