SpamAssassin and ClamAV

[Chris]

I'm new to Ubuntu so be nice. I've installed SA and ClamAV on my new
14.04 LTS system both from the repositories, SA is up and running
however, when SA tries to call the clamav.pm I get:
chris at localhost:~$ sa-learn --dump magic
plugin: failed to parse plugin /etc/spamassassin/clamav.pm: Can't locate
File/Scan/ClamAV.pm in @INC (you may need to install the
File::Scan::ClamAV module) (@INC contains:
lib /usr/share/perl5 /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl) at /etc/spamassassin/clamav.pm line 14.
BEGIN failed--compilation aborted at /etc/spamassassin/clamav.pm line
14.
Compilation failed in require
at /usr/share/perl5/Mail/SpamAssassin/PluginHandler.pm line 109.

File::Scan::ClamAV is impossible to install as shown in this output:

and I can't find it using apg-get unless I'm looking for the wrong
filename. 

Any help/advice would really be appreciated
