libcurl HTTPS issues on FreeBSD

[wagenet]

I'm not certain whether this is actually Rustup's fault, but I'm having issues with https connections in Rustup on FreeBSD.

$ curl https://sh.rustup.rs -sSf | sh -s -- -y
info: downloading installer
info: syncing channel updates for 'stable-x86_64-unknown-freebsd'
error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256' to '/home/vagrant/.rustup/tmp/4lfxi8knrpct9x3e_file'
info: caused by: error during download
info: caused by: [1] Unsupported protocol (Protocol "https" not supported or disabled in libcurl)

Curl claims to support https and when I try to hit an https URL directly with it, it works.

$ curl -V
curl 7.53.1 (amd64-portbld-freebsd10.3) libcurl/7.53.1 OpenSSL/1.0.1t zlib/1.2.8 nghttp2/1.21.1
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz TLS-SRP HTTP2 UnixSockets HTTPS-proxy

I'm also not seeing multiple libcurls installed either...

$ locate libcurl

$ locate bin/curl

Anyway, my apologies if this is not actually Rustup's fault.
