My pkg-config manpage (0.19) does not document Requires.private, but does 
have Libs.private.

What did you use to generate those?

Anyways, I don't see the same problem in my own package builds. (I am a 
pkgsrc developer and maintainer.)

For example, my libXpm only has NEEDED of libX11.so.6. (ldd does show the 
-lXau.6).

What does "objdump -p /path/to/bin/xman | grep NEEDED" show for you?
