  Rebuilt this and many other font packages or packages with build scripts
  that call mkfontdir or mkfontscale to suppress any error messages caused
  by collisions if another package installation is writing files to the
  same font directories when those utilities are run. In that case, the
  other package will also be running mkfontdir/mkfontscale after the files
  are installed, so any issues will be cleaned up then. Last one out turn
  off the lights, so to speak.
