[Lazarus] Error when building with my package. What's the problem?

[Anthony Walter]

Error received:

project1.lpr(20,1) Error: Undefined symbol: RTTI_$CODEBOT.SYSTEM_$$_DEF38

I updated FPC/Lazarus from svn sources recently and am attempting to
rebuild my personal source code packages. When I try to add these packages
to the IDE and rebuild, or even when I try to build a project with my
package as a requirement I am receiving the error message above and the
builds stop.

Does anyone know what the error of at the top of this message signifies and
how to fix it?

My package units use dotted the naming conventions such as:

Codebot.System in 'codebot.system.pas'
Codebot.Networking.Web in 'codebot.networking.web.pas'

I am not sure if this is contributing to the error. For reference here are
package sources:
