Hello all,

*I apologize for the length of this message*

I'm back and I have successfully built 100% of the modules (hooray!); 
until I attempt the above step (compile PNGDriver) on Darwin 1.4 (Mac OS 
X 10.1), at which point I get:

[localhost:display/devices/PNGdriver] root# gcc -O2 
-I/usr/src/grass/src/include -I/usr/local/include -I../lib -I/sw/include 
-c Color.c -o OBJ.powerpc-apple-darwin1.4/Color.o
png.h:23: Neither PNG nor GIF supported
cpp-precomp: warning: errors during smart preprocessing, retrying in 
basic mode


Any ideas?

I suppose it is related to the failed "gdImageGif"  and "gdImagePng"  
config section:


checking for location of PNG includes... /usr/local/include
checking for png.h... yes
checking for location of PNG library... /usr/local/lib
checking for png_read_png in -lpng... no
configure: warning: *** Unable to locate PNG library.
checking for location of GD includes... /usr/local/include
checking for gd.h... yes
checking for location of GD library... /usr/local/lib
checking for gdImageCreate in -lgd... yes
checking for gdImageGif... no
checking for gdImagePng... no


Note that I have built and installed GD successfully with PNG support 
and without GIF support (GIF is no longer supported by GD for obvious 
reasons).

To successfully build the PNG modules I had to hard-code libpng.a in as 
in:

  [localhost:src/raster/r.out.png] root# cc  -o 
/usr/src/grass/dist.powerpc-apple-darwin1.4/etc/bin/cmd/r.out.png 
OBJ.powerpc-apple-darwin1.4/r.out.png.o 
/usr/src/grass/src/libes/LIB.powerpc-apple-darwin1.4/libgis.a 
-I/usr/local -L/usr/local /usr/local/lib/libpng.a -lz

I appreciate any help.
