>Description:
As fedora packages are usually installed with /usr prefix most
third-party configs end up in /etc. bsd.port.mk enforces /usr/local
prefix by default but linuxulator only tries /compat/linux and falls
back to a path without prefix.

A few well known packages already have symlinks as part of linux_base:
openldap, fontconfig (fonts.conf). However, linux_base is mostly
unmaintained these days, so why not add symlinks to the packages that
install linux equivalents (e.g. ports/169896).

2012-10-15 version 310.14 (from NVIDIA_Changelog)

    * Implemented workarounds for two Adobe Flash bugs by applying libvdpau
      commit ca9e637c61e80145f0625a590c91429db67d0a40 to the version of libvdpau
      shipped with the NVIDIA driver.
>How-To-Repeat:
1. install multimedia/libvdpau
           www/linux-f10-flashplugin11
           www/nspluginwrapper
2. add ktrace -i -f /tmp/npviewer.$$ just after exec in
   /usr/local/lib/nspluginwrapper/noarch/npviewer.sh
3. launch firefox with some flash video
   
$ kdump -f /tmp/npviewer.68625 | fgrep vdpau_wrapper
 68625 npviewer.bin NAMI  "/compat/linux/etc/vdpau_wrapper.cfg"
 68625 npviewer.bin NAMI  "/etc/vdpau_wrapper.cfg"

$ ls /compat/linux/etc/vdpau_wrapper.cfg /etc/vdpau_wrapper.cfg
ls: /compat/linux/etc/vdpau_wrapper.cfg: No such file or directory
ls: /etc/vdpau_wrapper.cfg: No such file or directory
Exit 1
