Yeah, pkg_mkIndex basically sources each file, or to quote the man page

   It does this by loading each file into a slave interpreter and seeing
   what packages and new commands appear (this is why it is essential to
   have package provide commands or Tcl_PkgProvide calls in the files,
   as described above).

At least fastload was the only one causing an issue.
