Gut fails compilation at openssl on Catalina

Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.

$HOST = x86_64-apple-darwin
$TARGET = x86_64-apple-darwin
openssl-sys = 0.9.58



It looks like you're compiling on macOS, where the system contains a version of
OpenSSL 0.9.8. This crate no longer supports OpenSSL 0.9.8.

As a consumer of this crate, you can fix this error by using Homebrew to
install the `openssl` package, or as a maintainer you can use the openssl-sys
0.7 crate for support with OpenSSL 0.9.8.

Unfortunately though the compile cannot continue, so aborting.

I have installed OpenSSL via MacPorts. It did not help. Will try to install pkg-config.

The conclusion so far:

• does not build on Catalina, due to the following:
• some dependent code requires openssl, the system provided one is too old
• installing openssl using macports requires pkgconfig for openssl to be found
• pkgconfig has a dependency on iconv, which leads to the issue reported in gut fails to compile, with two error messages #141

These issues were not present before I upgraded to Catalina.

@snomos i've got the same issue on debian 10...

error: failed to run custom build command for `openssl-sys v0.9.58`

saw another thread indicate the need to install the libss-dev on debian... i'm thinking this is an issue with an old openssl library dep... going to explore that next

apt install libssl-dev

libssl-dev is already the newest version (1.1.1d-0+deb10u3).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

update:

sorry i solved my own problem on debian i just had to install pkg-config #facepalm

This just requires changing reqwest to use rustls instead of openssl.
