I would think that the doinst.sh script(s) that are included in the package, would (maybe) take care of all the details upon installation, but just in case, try the following:
1) install the font(s)
2) enter the folder where the fonts were installed.
shell# fc-cache -r -v
Optionally/additionally, as your regular user, enter your ~/.fonts folder (or create it of there is none) and repeat the above three commands as regular user.
Log out and restart X.
