An Ubuntu package of Petite Chez Scheme seems to be a common request among students, given the popularity of Ubuntu among the techno-capable. Currently, only RPM packages are provided on the Chez Scheme site, and the traditional recommendation was to use alien to convert the RPM into a .deb. There’s no reason to have everybody do this though.
I’ve built a .deb package of Petite Chez Scheme for amd64 (64-bit) Ubuntu 10.10. You should be able to install it by simply double-clicking the package and following the on-screen prompts. Petite can then be run using the terminal command `petite`.
