If the philosophy behind slackbuilds is to install into $PKG, then
hand $PKG to makepkg (which makes the package), and then hand the
package to installpkg (which does the actual install), then an
alternate approach to the current slackbuild might be:

  1) remove line 67
  2) put a similar line in doinst.sh
    ln -sf /opt/pdfstudioviewer2024/pdfstudioviewer2024 /usr/bin/pdfstudioviewer2024

My understanding is that the current SlackBuild installs a file in
/opt during the package build phase.  Even if the package is never
installed.

Unless I _really_ don't understand what is going on...

Regards,
Douglas.
