 The MacPorts user-agent is e.g.:

 {{{
 MacPorts 2.2.0 libcurl/7.24.0
 }}}

 [http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.43 RFC 2616
 section 14.43] defines the user agent as:

 {{{
 User-Agent     = "User-Agent" ":" 1*( product | comment )
 }}}

 [http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.8 RFC 2616
 section 3.8] defines `product` as:

 {{{
 product         = token ["/" product-version]
 product-version = token
 }}}

 It gives the following examples:

 {{{
 User-Agent: CERN-LineMode/2.15 libwww/2.17b3
 Server: Apache/0.8.4
 }}}

 So the MacPorts user-agent should be changed to e.g.:

 {{{
 MacPorts/2.2.0 libcurl/7.24.0
 }}}
