Oups, made an error in my previous follow up. I personnally added the
AppenTo[$Path .... thing in the sysinit.m file in the directory
C:\Program Files\Wolfram
Research\Mathematica\5.1\SystemFiles\Kernel\SystemResources\Windows
(obviously a Windows installation)
and not the init.m file in the directory
C:\Program Files\Wolfram Research\Mathematica\5.1\Configuration\Kernel

"ExtraPackages" and "Enhancements" likewise appear unnecessary, uninformative, and redundant. Is there a user package that ISN'T an added-on, extra, enhancement? I don't think so.
