compiling JOVE on Personal Iris

[RIE at PSUVM.BITNET]

I tried to compile JOVE 4.14 (only version avaiable from cs.rochester.edu)
without luck!
In the Makefile LIBS = -lbsd -lcurses and CFLAGS= -O -I/usr/include/bsd
was specified.
In the file sysdep.h i ensured that UNIX SYSV , SYSVR2 , SYSVR3 was defined
by taking out the comments from appropriate lines (3 lines).
While compiling JOVE i got the following error message during linking xjove:
/usr/bin/ld:
Undefined:
gldav

This is the only error message that i get.
Any suggestions to correct this error would be highly appreciated.
Thanks,
                                      Subhransu Roy
