Personally, I'm at a bit of a loss, without a little more information.

Couple of things come to mind;
In detail. What procedure did you use to build/install this module?
Did you tell Perl where you intended to install it

make install PREFIX=/path/to/my/personal/directory
[download]

Any more specifics, that you don't feel are typical of a normal/usual install would help.

Best wishes.
