Build failed while making procul

[officialcjunior]

Hello, I was trying to build procul but was met with this error:

error[E0432]: unresolved import `syn::export`
  --> /home/cjunior/.cargo/registry/src/github.com-1ecc6299db9ec823/enumset_derive-0.5.0/src/lib.rs:10:10
   |
10 | use syn::export::Span;
   |          ^^^^^^ could not find `export` in `syn`

error: aborting due to previous error

For more information about this error, try `rustc --explain E0432`.
error: could not compile `enumset_derive`

I did ask around at Rust's Discord and they said that it was probably was a semver-incompatible breaking change in the syn crate.
I tried updating the dependencies which didn't fix the issue, too.

Hey there, sorry but I stopped development on this a long time ago. I've been meaning to get back into rust but I'll probably have to rewrite a bunch of things to bring it up to speed with 2 years worth of rust updates.

Hey, thanks for the reply.
I just wanted to let you know about it.
