Well I am asking it here since "the feature" provided by heliohost, that is supposed to "install it automatically" does not, and at least that's why I thought you should be willing to help out people or suggest a work-around for this problem. If not, I believe it is best you do not include fantastico or at least "automatic installation of phpauction 2.1" as a part of what is being offered.
I will ask it to the people who made it and post anything I learn here anyway, just since there it has been viewed so many times.
Best regards.
