Requires vs Requires.private ?

[Denis Leroy]

So what is up with the "Requires.private" entries in various pkgconfig
.pc files ? Most mock fc5 builds are currently failing because of a
missing dependency between libX11-devel and libxau-devel. Culprit seems
to be :

bash-3.00# grep -i requires /usr/lib/pkgconfig/x11.pc
Requires: xproto kbproto inputproto
Requires.private: xau xdmcp
