Comment (by kencu):

 using the existing {{{cargo}}} it is possible to build a new {{{cargo}}}
 from source like this:
 {{{
 mkdir test
 cd test
 git clone https://github.com/rust-lang/cargo.git
 cd cargo
 RUSTFLAGS="-C link-args=/opt/local/lib/libMacportsLegacySupport.a"
 DYLD_FORCE_FLAT_NAMESPACE=1
 DYLD_INSERT_LIBRARIES=/opt/local/lib/libMacportsLegacySupport.dylib
 OPENSSL_DIR=/opt/local cargo build --features curl-sys/force-system-lib-
 on-osx --verbose
 cd target
 cd debug
 ./cargo
 }}}

 that seems unencumbered, although it's a debug version it seems and
 therefore is 10x larger than the original.

 (I did have to deactivate libiconv for the link, as it found MacPorts
 version, but I'm sure that is surmountable).
