Cairngorm Module Library - RSLData error with Flex 4.1 & Parsley 2.4

After upgrading a project from Parsley 2.3.2 to Parsley 2.4.0 I'm am experiencing the following error when compiling in Flex 4.1

1046: Type was not found or was not a compile-time constant: RSLData.

As part of the change I upgraded some of the Cairngorm librarys for Parsley 2.4 support but it appears that Module 0.17 is dependant on Flex 4.5? Is my assumption correct?

Here are a full list of the dependenies upgraded for reference:

• com.adobe.cairngorm.module 0.17 (Upgraded from 0.15)
• com.adobe.cairngorm.navigationParsley 1.7 (Upgraded from 1.3)
• com.adobe.cairngorm.integrationParsley 0.17 (Upgraded from 0.15)
• org.spicefactory.parsley-flex4 2.4.0 (Upgraded from 2.3.2)
• org.spicefactory.spicelib-flex 2.4.0 (Upgraded from 2.3.2)
  

Additional dependencies which weren't changed:

• com.adobe.cairngorm.task 1.10
• com.adobe.cairngorm.validation 1.12
• com.adobe.cairngorm.popup 1.13
• com.adobe.cairngorm.popupParsley 1.13
