missing dependence namazu2-index-tools

[Hiromu Yakura]

I installed namazu2-index-tools and ran `mknmz -a -t text/plain <directory>`.
But this package said that "Can't locate NKF.pm in @INC (@INC contains: /usr/share/namazu/filter /usr/share/namazu/pl . /etc/perl /usr/local/lib/perl/5.12.4 /usr/local/share/perl/5.12.4 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.12 /usr/share/perl/5.12 /usr/local/lib/site_perl) at /usr/bin/mknmz line 951."
Then I installed libnkf-perl and tried to run before command.
But even this package said that "Can't locate Text/Kakasi.pm in @INC (@INC contains: /usr/share/namazu/filter /usr/share/namazu/pl . /etc/perl /usr/local/lib/perl/5.12.4 /usr/local/share/perl/5.12.4 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.12 /usr/share/perl/5.12 /usr/local/lib/site_perl) at /usr/bin/mknmz line 956."
After I installed libtext-kakasi-perl, I was able to run before command.

I think namazu2-index-tools dependence to libnkf-perl and libtext-kakasi-perl
