The error indicates that x11.pc can't be found, which means that either
you have libX11 installed into a nonstandard location (a custom build
that overrides default locations perhaps), or you do not have the
development packages installed for libX11, etc.

If you're using Fedora Core:

yum install libX11-devel xorg-x11-proto-devel libXau-devel

or similar instructions for dpkg based distros, using apt.  If you're
not using rpm or dpkg based X installation, then you need to use your
distribution's installation method to install the X development
packages, or manually install them from source or whatever is most
appropriate.
