[Koha] Problems with subject searching

[Michael Watson]

I am working with Koha 2.0.0. Subject searching doesn't seem to be working. 
When I try an "Advanced Search->Search on Subject" in the opac, I get zero 
retrieval, even when I know for certain that I've created items in the 
catalog with that subject. 

I'm wondering if the problem is that I need to define mappings in 
parameters->links koha MARC Db. I see a message there saying that if I change 
the link between a MARC subfield and a non-MARC field, I need to run the 
misc/rebuildnonmarc.pl script. But when I try to do that, I get an error 
message that says that the script can't locate C4/Content.pm in @INC (error 
message follows).

./rebuildnonmarc.pl
Can't locate C4/Context.pm in @INC (@INC contains: /usr/lib/perl5/5.8.1/
i586-linux-thread-multi /usr/lib/perl5/5.8.1 /usr/lib/perl5/site_perl/5.8.1/
i586-linux-thread-multi /usr/lib/perl5/site_perl/5.8.1 /usr/lib/perl5/
site_perl /usr/lib/perl5/vendor_perl/5.8.1/i586-linux-thread-multi /usr/lib/
perl5/vendor_perl/5.8.1 /usr/lib/perl5/vendor_perl .) at ./rebuildnonmarc.pl 
line 10.
BEGIN failed--compilation aborted at ./rebuildnonmarc.pl line 10.

I know the location of the C4 directory, which does contain a Context.pm. This 
seems like some kind of path error--the directory containing this module 
evidently isn't stored in @INC. I tried pushing it there by adding a line to 
readuilbnonmarc.pl, but that didn't work. Does anyone know what the problem 
might be?

For what it's worth, I've run into some path problems previously with Koha on 
SuSE Linux 9.0 professional.
