Presumably because you don't have the X11 devel headers available.
For an rpm system, look for packages like x11-devel or some such.

Rpy also needs libR.so.  So regardless, your first task is to setup up
your system for compiling R from sources so you can get the .so.  It
shouldn't be too bad.  Pay attention to the output of configure.  When
it complains about things, try to find a PKGNAME-devel.rpm package to
install and try again.
