umar's questions

On my system 8.04, curl 7.18.0 is installed:

curl --version shows:

curl 7.18.0 (i486-pc-linux-gnu) libcurl/7.18.0 OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.1
Protocols: tftp ftp telnet dict ldap ldaps http file https ftps 
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz 

According to https://github.com/toland/patron/issues/25 , I need to install a later version of curl, example 7.19.4, in order to get it to work with patron. What is the process to update curl from 7.18.0 to a later version, example 7.19 or 7.20?
