I think the correct way is to specify -L/usr/pkg/lib
To get /usr/pkg/include in the include path, add -I/usr/pkg/include to
the compile line.
Some packages, like pthreads will actually require
LD_LIBRARY_PATH is used when the program is acutally run, so the OS knows
where to go looking for libraries if if doesn't find them in the standard
Hope that helps.
