Hi Tania!

You should probably download bioperl 0.7 if you get a chance...

I think instead of 
     -remote => 'local',
you should say
     -method   => 'local',

Also, you may need to customize the local blast module to fit your
site...

Because of the -remote argument it is invoking Webblast, which tells you
that extra modules not required at BioPerl install time are needed to 
use this module (this is so people who are never going to run networked
modules don't need to install superfluous code).
