newbie help wanted with installing/using netpbm through macports

[Matt]

Hi Ryan,

Thanks for the help.

I did find the following in the makefile for ppmtomd:

# if your ppm libraries are not in a standard place, uncomment
# and change this. You may also need thing like -R, but if you're
# on that sort of system you probably know it!
# LDLIBS = -L/usr/local/lib

I uncommented and changed the line to:

LDLIBS = -L/opt/local/lib

I also added your:

export CFLAGS="-I/opt/local/include"
export LDFLAGS="-L/opt/local/lib"

to my ~/.profile

Unfortunately, it still can't find those two header files on compiling.

Do I need to add something more to the makefile that points to -I/opt/ 
local/include?

Thanks!

-Matt
