How to download builds from macports?

[PavelTurk]

Hi all,

We have a Java project that must work on linux, windows, mac. To make project cross-platform
we provide jars with shared libraries - so, dll. These libraries are dowloaded with .sh script while
jar is built. We have libraries for linux and windows, but mac library is on macports.

Could anyone say how to donwload build/package, for example, for project `ffmpeg` using curl or wget?
Or what is the link to to it - http/https?

Best regards, Pavel
