[arch-general] per error

[message]

Readers,

'get_iplayer' is a program to extract media from BBC F(/tr)ash streams. 
After installation of the program, obtained the following error:

Can't locate HTML/Entities.pm in @INC (you may need to install the 
HTML::Entities module) (@INC contains: /usr/lib/perl5/site_perl 
/usr/share/perl5/site_perl /usr/lib/perl5/vendor_perl 
/usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl 
/usr/share/perl5/core_perl .) at ./getiplayer line 58.
BEGIN failed--compilation aborted at ./getiplayer line 58.

line 58:
use HTML::Entities;

Tried re-installation of perl (518222 already installed) and failed.

Any suggestions to solve please?
