Guile 1.3.* has built-in support for limited debugging, but this functionality is conditional on the package being configured & built with the "--enable-guile-debug" option. While perhaps the presence of this code slows down non-debugging sessions a bit, its absence causes grief when debugging Scheme code. The unavailability of stack tracebacks are a real killer. Please build the guile RPM with this additional configure-time flag.
We have considered your request here but unfortunately have to inform you that we will not enabled the debuging option for the builds. If you need assistance in how you can rebuild the guile RPM with the debugging enabled feel free to drop me an email. Read ya, Phil <phil>
