rtld and entropy depletion issues aside, the recurring breakage 
has been due to insufficient test coverage of updates before commit.
Switching to a binary distribution to solve that seems like
capitulation to me.

If developers don't have time or hardware to properly test their
changes they should post the diff on #pkgsrc or tech-pkg@ to get
testing on at least one other OS and/or version before landing the
update. That alone will go a long way to improve lang/rust stability.

Correct. The default behaviour of "make" in pkgsrc should be to build
packages from source at all times, unless the user explicitly requested
otherwise with DEPENDS_TARGET, RUST_TYPE or similar.
