 If you're building using a sandbox with null mounts (I assume you are),
 then compat80 won't be installed effectively, as it wants to reach
 outside the sandbox to write symlinks under /usr/lib, which gets
 rejected. (compat80 breaks pkgsrc norms by writing outside $PREFIX.)
 
 The hackish way around that for a specific, dedicated build environment
 is simply to install compat80 outside the sandbox. Another way could be
 to use something like the kludge I introduced for the ghc* packages[1],
 though Rust may be a little more complicated. (I did note this in my
 commit message when I restored the compat80 dependency[2]; I guess
 maybe it would have been better if I'd written a comment above. I was
 at the point of frustration with our Rust packaging that I didn't want
 to deal with it further. I'm almost at that point again today.)
