Loading configuration file /Developer/flex_sdk_3/frameworks/flex- config.xml /Users/RayMerkler/ueca/com/hindrances/ueca/Ueca.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'com.hindrances.ueca'.
The package declaration inside the Ueca.as class needs to reflect the directory structure that contains it. So, in this instance, it's logically "package com.hindrances.ueca {" however you don't have the conventional src/ or source/ directory to identify the source root. You may need to check what the compiler expects the source root to be and adjust it's settings accordingly.
If you update the bundle I have added an exception catch to the script which parses mxmlc output. This means that any lines that aren't matched will now reach the output window as raw text.
