Thanks for this hint! But were to add it (sorry, speak slowly please).
I tried to add it in PNGdriver/Gmakefile but it still picks up
the wrong lib:

gmake5
[...]
gcc -L/hardmnt/thuille1/ssi/cvsgrass_exp/src/libes/LIB.i686-pc-linux-gnu  -o
/ssi0/ssi/neteler/cvsgrass_exp/dist.i686-pc-linux-gnu/driver/PNG
OBJ.i686-pc-linux-gnu/Can_do.o OBJ.i686-pc-linux-gnu/Clr_table.o
OBJ.i686-pc-linux-gnu/Color.o OBJ.i686-pc-linux-gnu/Draw_line.o
OBJ.i686-pc-linux-gnu/Get_w_box.o OBJ.i686-pc-linux-gnu/Get_w_line.o
OBJ.i686-pc-linux-gnu/Get_w_pnt.o OBJ.i686-pc-linux-gnu/Graph_Clse.o
OBJ.i686-pc-linux-gnu/Graph_Set.o OBJ.i686-pc-linux-gnu/Panel.o
OBJ.i686-pc-linux-gnu/Polygn_abs.o -ldriver -lgis -lz   -L/usr/local/lib
-lgd -lfreetype   -ljpeg   -lpng  -lz  -lm -Wl,-soname,libgd.so.2

[sorry, I don't know anything about this soname trick]

ldd /ssi0/ssi/neteler/cvsgrass_exp/dist.i686-pc-linux-gnu/driver/PNG
        libgd.so => /usr/lib/libgd.so (0x40017000)

ls -l /usr/lib/libgd.so
lrwxrwxrwx 1 root root 14 Aug  1  2001 /usr/lib/libgd.so -> libgd.so.1.8.3

Well, even for us here at IRST I need a solution, an 8bit PNG driver
ist just too poor.
