Lost XFree86-4

[Bob Perry]

I just deinstalled XFree86 -4.X and built XFree86 3.X in error.  I
deinstalled XFree86 3.x before setup and tried use the ports collection to
install XFree86 4.3.0,1.  The process began indicating that XFree86-4.3.0,1
depended on shared library : X11.6 which was "not found".  It began to
configure XFree86-libraries-4.3.0_5 but was unable to locate two files:
/usr/X11R6/lib/X11/config/host.def, and
/usr/X11R6/lib/X11/config/xf86site.def.  Shortly afterward I received a
series of "Error code 1" messages:

Stop in /usr/ports/x11/XFree86-4-libraries/work/xc.
Stop in /usr/ports/x11/XFree86-4-libraries/work
Stop in /usr/ports/x11/XFree86-4-libraries/
Stop in /usr/ports/x11/XFree86-4

My  problems originated while I was unsuccessful at upgrading
XFree86-FontServer and XFree86-client due to a missing font lXfont.  I was
trying to remedy that situation when I fouled up here.

I'm running FreeBSD-RELEASE 4.7 and would appreciate some advice as to how I
can cleanly get things back to normal.

Thanks in advance and have a happy holiday.
