Where is xperfmon?

[rouben at math9.math.umbc.edu]

I am looking for the latest version of xperfmon, a program for graphic
display of system activities under X window system.  I do have the source
released with the X11R4 distribution tape, but I have difficulty compiling
it on ULTRIX 4.0.  I get the following error message:

cc -O -c system.c
ccom: Error: system.c, line 279: v_intr undefined

I would appreciate any information on the ftp sites that may have the
latest patches to xperfmon.
