[R-SIG-Mac] Problems updating RCurl on Yosemite

[peter dalgaard]

In general, homebrewers get to drink their own booze. (i.e., we don't support it.) 

However, for R itself, it is necessary for me to set CURL_CONFIG in order not to pick up the curl-config from MacPorts. You might want to check if you are running into the same issue in reverse.
