CLI: build process does not lookup modules the same way as ti module

When i set a custom module path using appc ti config paths.modules "mycustom/path", the modules I put in here are not recognized in the build command.

I checked using the appc ti module command, and my module is listed under Configured Path Modules, and not under Global Modules (which is correct). However, the one under Configured Path Modules points to the correct path but it is not recognized during build, and therefore it throws:

[ERROR] Could not find all required Titanium Modules:

[ERROR]    id: com.mymodule	 version: 1.1.0	 platform: iphone	 deploy-type: development

The desired situation checks both the default directory (the global one under "~/Library/Application Support/Titanium/modules"), but also the custom directory added using the config file.
