Today I downloaded the  mplayerplug-in-3.17.tar.gz file from the homepage.  I used the following configure commands:

./configure --prefix=/usr  --enable-wmp --enable-qt --enable-rm  --enable-gmp

I have two questions:

1. How can I tell it to also link again /usr/lib/firefox, since it's only finding mozilla?

2. The bug is being shown here:

Installing plugin system wide
Installing into ${moz_libdir}/plugins
mkdir: cannot create directory `${moz_libdir}/plugins': No such file or directory

which then throws it into my source tree directory:

bash-3.00# ls -l | head -5
total 19369
drwxr-xr-x  3 root     root       72 2005-12-31 12:42 ${moz_libdir}

Is it a bug, or something in my build?
