Ruby-audio from AUR fails to build [SOLVED]

Question

I'm attempting to install ruby-audio from AUR.  Got the PKGBUILD file.  Running makepkg results in a complaint about options for an install directory.   I'm not expert enough at the ruby ecosystem and gem to see any obvious problem.  What is the fix? 
=> makepkg
==> Making package: ruby-audio 1.6.1-1 (Mon Jun 16 09:51:10 PDT 2014)
==> Checking runtime dependencies...
==> Checking buildtime dependencies...
==> Retrieving sources...
  -> Found ruby-audio-1.6.1.gem
==> Validating source files with md5sums...
    ruby-audio-1.6.1.gem ... Passed
==> Extracting sources...
==> Removing existing pkg/ directory...
==> Entering fakeroot environment...
==> Starting package()...
ERROR:  Use --install-dir or --user-install but not both
==> ERROR: A failure occurred in package().
    Aborting...
Apparently the error is in the package() routine in PKGBUILD:
package() {
  cd "$srcdir"
  # _gemdir is defined inside package() because if ruby[gems] is not installed on
  # the system, makepkg will exit with an error when sourcing the PKGBUILD.
  local _gemdir="$(ruby -rubygems -e'puts Gem.default_dir')"
  gem install --ignore-dependencies -i "$pkgdir$_gemdir" -n "$pkgdir/usr/bin" \
    "$_gemname-$pkgver.gem"
A search here in the Arch forums turned up nothing.

package() {
cd "$srcdir"
local _gemdir="$(ruby -e'puts Gem.default_dir')"
gem install --ignore-dependencies --no-user-install -i "$pkgdir/$_gemdir" -n "$pkgdir/usr/bin" $pkgname-$pkgver.gem
rm "$pkgdir/$_gemdir/cache/$pkgname-$pkgver.gem"
