Pb option in a new convertor DVI -> PDF

[Yves Bergeon]

Hi,
I am trying to use a convertor DVI-> PDF, which name is dvipdf (ghost
6.50).
It's OK by hand, but when I try to use it from lyx, I had a window with
this
message: 
Error while executing dvipdf -p letter 'file_name.dvi' 'file_name.pdf'

This is normal, because -p letter is not an option. So, how to avoid the
string
-p letter ? (I didn't define it).

Thanks
