So, I have tried to rebuild 'hylafax+' with 'urw-base35-fonts' and it passed:
https://koji.fedoraproject.org/koji/taskinfo?taskID=22352204

I suggest we rebase it newer version (5.5 -> 6.0.6 -- the latest stable release is already 5 years old -- http://www.hylafax.org/content/Download), rebuild it against 'urw-base35-fonts', and get it to Rawhide for testing.
