[GRASS5] Compiling 51

[Harald Wehr]

I want to test the vector support in 51, but got an error during the 
compilation:

make[3]: Entering directory `/home/Geo/GRASS/grass51/display/d.mon/cmd'
make[3]: *** No rule to make target `-lpq', needed by
`/home/Geo/GRASS/grass51/dist.i686-pc-linux-gnu/etc/bin/cmd/d.mon'.  Stop.
make[3]: Leaving directory `/home/Geo/GRASS/grass51/display/d.mon/cmd'
make[2]: *** [subdirs] Error 1
make[2]: Leaving directory `/home/Geo/GRASS/grass51/display/d.mon'
make[1]: *** [subdirs] Error 1
make[1]: Leaving directory `/home/Geo/GRASS/grass51/display'
make: *** [default] Error 1

This error has occured to other users too. But there is no solution 
given in the archive. See also:

Can you give me any hints how to solve the problem?

Thanks in advance

Harald
