We're developing web parts using log4net as the logging framework. Right now we're leaving the configuration details in the web.config and will be moving the log4net.dll to the GAC manually.
For a small development team (2 devs) and an internal sharepoint installation, is that adequate? I've read about using WspBuilder, creating a setup project, a globablly scoped solutions, and so on for deployment but We really aren't going to have that much custom code. Most of our sites will be using out-of-the-box or third-party web parts along with Enterprise features like the Business Data Catalog and Reporting Services.
