Finally LambdaRogue is working on MacOS Lion. Today, I re-installed XCode, re-installed FreePascal, and re-compiled the source code. The resulting binary is now Intel-only, as Lion does not support PowerPC anymore. Sorry about that; not my fault.
You can download the new binary at SourceForge:
http://sourceforge.net/projects/mac-lambdarogue/files/LambdaRogue%201.6/LambdaRogue_1.6_MacOS_Lion.zip/downloadThe .zip-archive also contains a new startup script, which allows you to place your LambdaRogue folder anywhere; i.e. you're not forced to have it in your Applications folder anymore.
To install the Lion patch, simply open the .zip and copy the content into your LambdaRogue folder. Replace any existing files.
