Comment (by kencu):

 To make cargo work on 10.9, you first make sure {{{git}}} is installed,
 then this magical incantation works:
 {{{
 export CARGO_NET_GIT_FETCH_WITH_CLI=true
 RUSTFLAGS="-C link-args=/opt/local/lib/libMacportsLegacySupport.a"
 DYLD_FORCE_FLAT_NAMESPACE=1
 DYLD_INSERT_LIBRARIES=/opt/local/lib/libMacportsLegacySupport.dylib cargo
 install ripgrep --verbose
 }}}
 and you get a very nice build of {{{ripgrep}}} with {{{rust}}} and it has
 {{{libMacportsLegacySupport.a}}} linked in statically, and (seems to)
 work:
