gv and libXaw3d

Found another small application that's not working, namely gv. The error message is:

dyld: Library not loaded: /usr/X11R6/lib/libXaw3d.7.dylib
  Referenced from: /usr/local/bin/gv
  Reason: image not found
Trace/BPT trap

so as before I looked in /usr/X11R6 1/lib, and lo and behold, there's the relevant library.

A quick

/usr/X11R6 1/lib:ls /usr/X11R6/lib/*Xaw3d*
ls: /usr/X11R6/lib/*Xaw3d*: No such file or directory
/usr/X11R6 1/lib:sudo mv *Xaw3d* /usr/X11R6/lib/

and gv is good to go again.
