On my system w/o the adobe fonts - I made the following:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- conf.d/sub-pixel.conf -->
<fontconfig>
        <alias>
          <family>Helvetica-Narrow</family>
          <accept><family>Nimbus Sans L Condensed</family></accept>
        </alias>
</fontconfig>

AbiWord (which uses fontconfig) still only used Nimbus Sans L for the
rtf that has both Hevetica and Helvetica-Narrow defined.

When I changed <family>Helvetica-Narrow</family> to <family>Helvetica
Narrow</family> (using space and not dash) and ran sed on rtf file to
change it there, it then behaved as it should.

So I think I might be able to figure out a with a match directive to
have it properly match Helvetica-Narrow (with the -) with the condensed
URW replacement - and if I do, I'll submit that as a patch to fedora
bugzilla.

But that would not solve the problem of having the real Helvetica-Narrow
installed reported in the bugzilla at the beginning of this thread,
where fontconfig is grabbing the metrics from Helvetica but grabbing the
shapes from Helvetica-Narrow.
