I can confirm this trick using Ubuntu Feisty:

I set up 2 symlink:
/usr/lib/pwlib$ ls -l
[...]
lrwxrwxrwx 1 root root   32 2007-09-03 18:02 libavcodec.so
-> /usr/lib/pwlib-cvs/libavcodec.so

and
/usr/lib/pwlib/codecs/video$ ls -l
total 4
lrwxrwxrwx 1 root root 69 2007-09-03 18:08 h264_video_pwplugin_helper
-> /usr/lib/pwlib-cvs/opal-2.3.2/codecs/video/h264_video_pwplugin_helper
