Since URW is the original copyright holder, the solution would be for
URW to either relicense the fonts themselves e.g. under LPPL or OFL -
whaterver FOSS license works best for fonts, or to give special
permission, i.e. an exclusive license, to GUST do so... I doubt URW
would care much either way after almost 20 years since these fonts
have GPL'd. But they need to be approached about the matter. I guess
Tom knows better what's the optimal way out in a situation like this.

In fact its even more explicit in that file:
"TeX Gyre Adventor is based on the URW Gothic L distributed under
GPL with Ghostscript."
and then
"The TeX Gyre Adventor family can be freely used and distributed
under the GUST Font License (see above) which is actually
an instance of the LaTeX Project Public License"
Madness! :-)
