rust-bin install error on macos 10.15

[Michael-John Turner <mj%mjturner.net@localhost>]

Hi all,

I'm trying to install lang/rust-bin from a pkgsrc HEAD tree on macOS 10.15
and am getting the following error:

---
install_name_tool -id /opt/pkg/lib/rustlib/x86_64-apple-darwin/lib/python2.7/site-packages/lldb/_lldb.so  /Volumes/pkgsrc/obj/lang/rust-bin/work/.destdir/opt/pkg/lib/rustlib/x86_64-apple-darwin/lib/python2.7/site-packages/lldb/_lldb.so
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open file: /Volumes/pkgsrc/obj/lang/rust-bin/work/.destdir/opt/pkg/lib/rustlib/x86_64-apple-darwin/lib/python2.7/site-packages/lldb/_lldb.so (No such file or directory)
*** Error code 1

Checking the contents of rust-1.47.0-x86_64-apple-darwin.tar.gz, I can't
see any references to python.

Should this be removed from the package Makefile?

install_name_tool -id ${PREFIX}/lib/rustlib/${RUST_ARCH}/lib/python2.7/site-packages/lldb/_lldb.so \

Cheers, MJ
