Unhappy g++ can't find libraries that are in /usr/lib

I'm trying to build a very small program that needs to reference some libraries at compile time. It's telling me that the libraries don't exist. They do exist. I've spent 30 hours or so installing all of them. I have the latest stable version of gcc.

I would greatly appreciate any help.
Thank you.

linux:/home/bill/supermemox-0.0.1/src # make
gcc -Wall -I. -o supermemox KnowledgeOrganizer.o KnowledgeCollection.o KnowledgeNugget.o LearningAlgorithm.o TestResult.o XmlSerializable.o XmlParser.o TextUI.o main.o -l expat -l boost_date_time -l nana -l stdc++
gcc: expat: No such file or directory
gcc: boost_date_time: No such file or directory
gcc: nana: No such file or directory
gcc: stdc++: No such file or directory
make: *** [supermemox] Error 1

Read the gcc/g++ manpage. You are not using the command correctly.

-I. is not neccesary.

Here is an example of me compiling a program with two cpp files in it and the expat library linked in:
g++ -Wall -lexpat -o foo foo.cpp bar.cpp
