I'm using WAMPSERVER for my development environment (MySQL v 5.1.553,
PHP v 5.3.4) . The software that I am modifying uses the MySQL
PASSWORD() function which works fine locally. After moving the code
and database to the production server (MySQL v 5.0.77, PHP v 5.3.3) I
cannot log in.
Is there anything other than the versions that could cause this
behavior? I was thinking maybe PHP extensions but I do not know what
the PASSWORD() function depends on.

Something changed about storing passwords in MySQL between version 4.x
and 5.0
A compatibility switch was introduced in 5.0
I think it no longer exists in 5.1
All info is here:
http://dev.mysql.com/doc/refman/5.1/en/password-hashing.html
If you have access to both systems check the output of:
SELECT PASSWORD('something');
and see if the output on both systems is the same,...

The documentation states that prior to MySQL 4.1, password hashes
computed by the PASSWORD() function are 16 bytes long which is what
the result is when I tried your suggestion (SELECT
PASSWORD('something')) on my production server but my production
server MySQL version is 5.0.77. My development server is returning 41
byte. I also never did an upgrade which the documentation suggests
upgrading to 4.1 and then to 5 or higher. I installed 5.0.77
directly. This seems strange to me...any suggestions?

on the link it says:
The way in which the server generates password hashes for connected
clients is affected by the width of the Password column and by the
--old-passwords option. A 4.1 or later .....
which refers to:
http://dev.mysql.com/doc/refman/5.0/en/server-options.html#option_mysqld_ol d-passwords

I suppose you are talking about your application users, not MySQL users.
You can use OLD_PASSWORD() if you need to emulate the old format in a
new system:
http://dev.mysql.com/doc/refman/5.1/en/encryption-functions.html#function_o ld-password
SELECT PASSWORD('abcd'), OLD_PASSWORD('abcd')
