How do I link with Aquaterm library for an external build?

Which is why we recommend you don't put anything in /Library/Frameworks (or /usr/local) if you want to use MacPorts.

Since I've fixed the problem with the solution above, this is not terribly important for you to answer, but would you mind showing me more explicitly how to add "-F/opt/local/Frameworks" and "-framework AquaTerm" to CFLAGS? I currently have no CFLAGS variable in my build script. Would I add a line like this?

Thanks, Ryan.

I entered this line with quotes in my script followed by
export CFLAGS
(and removed the symlink I mentioned earlier) but Aquaterm was not found--PLplot still builds without the Aquaterm option. There are lots of occurrences of things like this which I don't understand:

cd /usr/local/plplot_build_dir/examples/c && /usr/bin/gcc   -F/opt/local/Library/Frameworks -framework AquaTerm  -I/Users/me/Documents/Programs/Ada/Code/Bindings/PLplot/plplot_svn/plplot/include -I/usr/local/plplot_build_dir/include -I/Users/me/Documents/Programs/Ada/Code/Bindings/PLplot/plplot_svn/plplot/lib/qsastime    -DUSINGDLL -o CMakeFiles/x33c.dir/x33c.c.o   -c /Users/me/Documents/Programs/Ada/Code/Bindings/PLplot/plplot_svn/plplot/examples/c/x33c.c
