Note that the "4" in libcurl.so.4 is not the version number of the
library. You can find out the libcurl version number by invoking
curl-config --version libcurl
On my system, this returns "7.21.0" even though the library is named
"libcurl.so.4".
For more information of the number after "so" in library names, check
