Frequently an installation is used to build other software. The bundles for this are called software development kits (SDK) and are a collection of 'dev' and 'rtl' packages. For this type of installation, an additional step is required to install whatever build flavors are needed. To install a set of flavors do the following:

gpt-build -nosrc LIST OF FLAVORS

If you have no idea what flavors are needed then do the following:

gpt-build -nosrc -std-flavors
