Font Problems -- Helvetica

["Johan van der Meer" <johanvandermeer@gmail.com>]

I haven't get the Helvetica Font on Ubuntu; is there some way to
automatically link to the Arial font with the use of a fonts.dir,
fonts.alias, or some other file, thereby tricking applications into
using Arial? And how would I go about doing that? I'm fairly new to
linux, and (thus) also using fonts on Xorg86.

One of my programs hangs when I try to run it. (display, from the
imagemagick toolbox; it complains it cannot find the helvetica font and
then stops).

Cheers,
Johan
