Hi, If you use the REPL, you may have something like this at the bottom of your ~/.guile       (set! repl-welcome (say "My Customized Guile")) So that the startup message is abbreviated and more specific to your environment. Commit 9b9149a5b somehow stops this from functioning.   Reverting that commit on top of the current development HEAD, restores the ability to set your own welcome message. Sorry I couldn't provide a better fix. Thanks much.
