Hi!

This failure is caused by Python 2's tarfile module not supporting
sparse files in archives. Python 3 supports them but the configure
script insists on using Python 2.

Before a proper fix is committed, you can change the following line in
lang/rust/Makefile:
https://github.com/freebsd/freebsd-ports/blob/master/lang/rust/Makefile#L159

to say (this is a single line):
gtar -c -C ${WRKSRC} -f -
rust-std-1.16.0-${RUST_ARCH_${ARCH}}-unknown-freebsd | gzip >
${WRKSRC}/rustc.tbz

Then, change the following line:
https://github.com/freebsd/freebsd-ports/blob/master/lang/rust/Makefile#L34

to say:
BUILD_DEPENDS= cmake:devel/cmake \
		gtar:archivers/gtar

This will use GNU tar instead of BSD tar to recreate the bootstrap and
GNU tar doesn't seem to produce sparse file entries in the archive.
