Using the 'import' function?
I apologize for the flippancy, but
- you haven't given us much to work with, and
- instead of using 'import', you really should be putting your classes into modules and relying on the autoloader.
If you want us to have any hope of troubleshooting the immediate problem then please provide the actual error message emitted by puppet and all the classes/*.pp files. For best results, find a minimal set and minimal content for the imported manifests that still exhibits the problem.
