This error indicates a conflict between the system version of libcurl (7.19.7 on OS X 10.6) and a more recent version installed by MacPorts. To work around the problem, force the use of the system version of libcurl with PATH=/usr/bin:$PATH sudo easy_install pycurl. Alternately, you can install python and pycurl via MacPorts (sudo port install python26 py26-curl) and use those instead of the system versions.
