Hi all--
If i try building rust-sequoia-openpgp (e.g. using debuild -uc -us) as a
non-privileged user on a system that has some unnecessary dependencies
installed, i will sometimes get a failure during build.rs that looks
something like the following (this example is from building on a system
that has the previous version of librust-sequoia-openpgp-dev installed):

-----
The key part of this failure appears to be during build.rs, when lalrpop
traversing into the custom "cargo_registry" that is built as a symlink
farm in debian/cargo_registry, where each symlink points to the matching
crate in the system-installed /usr/share/cargo/registry/
The relevant line in build.rs is line 10, where lalrpop::process_root()
is invoked:
7 fn main() {
8 crypto_backends_sanity_check();
9 include_openssl_conf();
10 lalrpop::process_root().unwrap();
11 include_test_data().unwrap();
12 }
I think this yields a "Permission denied" error when run over a
directory that the user can't write to, but i haven't investigated
further.
It's possible that this report should be applied to one of the lalrpop
crates or something, instead, if the issue isn't something that should
be fixed in build.rs in the sequoia-openpgp crate. Feel free to
reassign with a clear explanation.
