[Koha] perl C4 module errors

[Matthew Metzger]

Hello,

I just upgraded from 2.2.6 to 2.2.9

I seem to be having problems with running some perl modules that come 
with koha, the C4 modules. Here's the error I get when I run this command:

sudo perl /usr/local/koha/intranet/scripts/updater/updatedatabase

Can't locate C4/Context.pm in @INC (@INC contains: /etc/perl 
/usr/local/lib/perl/5.8.7 /usr/local/share/perl/5.8.7 /usr/lib/perl5 
/usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 
/usr/local/lib/site_perl .) at 
/usr/local/koha/intranet/scripts/updater/updatedatabase line 23.
BEGIN failed--compilation aborted at 
/usr/local/koha/intranet/scripts/updater/updatedatabase line 23.


How can I permanently add the C4 modules to the @INC variable? Is there 
some other solution that is better?

The z39.50 search is also not working and I'm assuming that this is the 
problem.

thanks for your time and any help you can give,

Matthew
