Ack, builddir should of been destdir and when I rerun the compile
destdir does what it should do. It also turns out it's not what I want.
It seems I want sitelib (but maybe I'm mis-understanding what sitelib
is):

>From the README:


Alternatively, you could specify the "sitelib" parameter when you run
the "Build.PL" script:

         perl Build.PL sitelib=/my/secret/place/

Under normal circumstances, you'll need superuser privileges to install
into your system's default "sitelib" directory.

I re-read your earlier message and I think I understand what your are saying now.

Yes, it's butt ugly and requires me to know about %Config and
what my archname is. I guess just setting sitelib isn't enough or
doesn't do what I thought it would do. Here's some output of Build,
I apologize for long lines below. I realize that it pass the tests
but it does issue warnings and it also shows the @INC problem and
it trying to install into a directory it doesn't have permission to.
Let me know how I can help (I'm about to try that patch you just sent out):
