Help .. Problem in starting monitor

[grassp-list@moon.cecer.army.mil]

I am using GRASS4.0 on UNIX SVR 4.0 with X11R4 and OPENLOOK.
I downloaded the files from moon and have compiled them on this 
system. The following changes were made during compilation.

* In directory  display/devices/XDRIVER
   file             Box-abs.c
   line no 60      /usr/include/X11/Xos.h
   Error          Cannot find include file   <strings.h>

   -DSYSV included at command line, to use SYSV header files

* In directory  display/devices/XDRIVER
   Ld Error         -lX11 not found 

   - lX11 replaced by
  /usr/X/lib/libX11.so /usr/X/lib/Xol.so /usr/X/lib/libXt.so -lnsl -lc
   as suggested by X manual at our site.

I was able to execute the complete script, without any problem.
However i have not been able to use GRASS. 

i am running it on a local-machine on which all the grass software, as
well as X software is residing. I am executing grass4.0 under X and
openlook.
 
Fifo's are all setup.

When i give d.mon command from grass4.0 prompt, and try to start
x0, it fails with the following message.

Error - Could not complete locking process for monitor <x0>
Lock file is 

Some of the programmes, like g.help is executing fine.
Looking for help, 
Thanks.
