Do you silently imply that libcurl _would_ be the best solution?
What about curl(1)?

Yes (I maintain the macport and the OpenBSD port of SoX).

This is how both the OpenBSD port and the macports
patches SoX 14.4.1:

The point is that these system have a ftp(1) in their basic
install that can do "ftp -o", and wget is a needless dependency.

Would ./configure be the proper place to make the decision?
What about curl(1)?
