 Installing MacPorts somewhere under $HOME is not uncommon. Using $HOME
 directly as the prefix and overriding CPATH and LIBRARY_PATH is.

 You can technically override MacPorts’ toolchain, yes, but we do not
 support doing so and are not obligated to accommodate such configurations.

 There very well might be a bug in libtool, but it’s not quite what you are
 describing. Anyone using MacPorts in the standard fashion gets a
 libarchive that is //not// linked to the system libraries.
