As an aside, Fedora's policy as I understand it is to explicitly exclude such static libraries from the packaging unless otherwise absolutely necessary. Once you install libX11-devel, you'll see various libX11.so symlinks in your /usr/lib directory (or /usr/lib64 if using a 64-bit arch). These are how the dynamic linker finds the appropriate library.
