Installation instructions failing

[phlummox]

I've been attempting to install podman-proxy by following the current installation instructions, which say to run

$ go install github.com/Dadard29/podman-proxy

However, using recent versions of go (I tried versions 1.17.1 and 1.19.1), this results in the error message:

go install: version is required when current directory is not in a module
	Try 'go install github.com/Dadard29/podman-proxy@latest' to install the latest version

Do the installation instructions need to be updated to reflect this?

If I follow the suggestion in the error message, add @latest to the URL, and run go install github.com/Dadard29/podman-proxy@latest, installation still fails: after the usual messages about packages downloading, go reports:

# pkg-config --cflags  -- devmapper
Package devmapper was not found in the pkg-config search path.
Perhaps you should add the directory containing `devmapper.pc'
to the PKG_CONFIG_PATH environment variable
No package 'devmapper' found
pkg-config: exit status 1
# github.com/mtrmac/gpgme
/go/pkg/mod/github.com/mtrmac/gpgme@v0.1.2/data.go:4:11: fatal error: gpgme.h: No such file or directory
    4 | // #include <gpgme.h>
      |           ^~~~~~~~~
compilation terminated.

I am assuming from this that podman-proxy has C library dependencies which aren't stated in the README. Could the installation documentation be updated to state what the prerequisites for a successful build are?
