You have not said what distribution you are using (or I missed it
if you did).  These may well be in a devel package that's not
loaded by default.  On SLES9, the package is XFree86-devel.  On
CentOS 5 (RHEL5), the package is libX11-devel.

The stamping of paper is an operation so much easier than the laying of
taxes, that a government, in the practice of paper emissions, would rarely
fail, in any such emergency [such as an election], to indulge itself too
far in the employment of that resource... -- Alexander Hamilton
