lang/rust still looks in /usr/pkg/

[John Klos <john%ziaspace.com@localhost>]

This problem still exists because rust is looking in /usr/pkg/:

running: /usr/pkgsrc/lang/rust/work/rust-bootstrap/bin/cargo build 
--manifest-path 
/usr/pkgsrc/lang/rust/work/rustc-1.47.0-src/src/bootstrap/Cargo.toml 
--frozen
/usr/pkgsrc/lang/rust/work/rust-bootstrap/bin/cargo: Shared object 
"libcurl.so.4" not found

What's the proper fix for this?

John
