MailScanner did not installed successfully in Fedora 11

[Richard R. Cahilig]

Hello,

I tried to install MailScanner in my Fedora 11 server but the 
installation did not went fine. I'm getting a lot of  errors like this 
one below.
"Missing file"
"Maybe it did not build correctly?"

Here is the output of the "MailScanner -v" and "MailScanner --lint" 
command that I ran.

Can't locate Filesys/Df.pm in @INC (@INC contains: /usr/lib/MailScanner 
/usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi

line 91.

Please help me.
