Glad you got things working. A few quick remarks:
1) You don't need to call ParseDir or CreateFromFiles. The loader will
figure out what files you need to load for each package; just call
config.Import(packagename).
2) The go/types tutorial says that export data doesn't contain position
information. That used to be true, but we have since extended the export
data format to include it. I'll update it.
3) That said, I did once notice a bug whereby the position of the package
declaration was reported instead of the correct location. If you are able
to reproduce that bug, please report it.
cheers
